Extraschicht , a yearly cultural event of the Ruhr region takes places, simultaneously with other locations, in the old Waltrop's mine building, now head office of the company. Hase Bikes holds the Guinness Book of Records record for the longest tandem in
148-424: A differential . A double freewheel , preferably using no-backlash roller clutches, is considered superior. Trikes with a differential often use an internally geared hub as a gearbox in a 'mid drive' system. A jackshaft drive permits either single or two-wheel drive. Tadpoles generally use a bicycle's rear wheel drive and for that reason are usually lighter, cheaper and easier to replace and repair. Some trikes use
222-492: A utility bicycle emphasizes comfort and has higher handlebars resulting in an upright riding position. Frame geometry also affects handling characteristics. For more information, see the articles on bicycle and motorcycle geometry and bicycle and motorcycle dynamics . Frame size was traditionally measured along the seat tube from the center of the bottom bracket to the center of the top tube. Typical "medium" sizes are 54 or 56 cm (approximately 21.2 or 22 inches) for
296-415: A European men's racing bicycle or 46 cm (about 18.5 inches) for a men's mountain bike . The wider range of frame geometries that now exist has also led to other methods of measuring frame size. Touring frames tend to be longer, while racing frames are more compact. A road racing bicycle is designed for efficient power transfer at minimum weight and drag. Broadly speaking, the road bicycle geometry
370-405: A complete tricycle. Conversion sets can also supplied ready to be brazed onto a lightweight, steel bicycle frame to form a complete trike. Some trike conversion sets can also be used with recumbent bicycles to form recumbent trikes. Adults may find upright tricycles difficult to ride because of familiarity with the counter-steering required to balance a bicycle. The variation in the camber of
444-411: A criterium (massed start racing) series. A delta tricycle has one front wheel and two rear wheels. A tadpole tricycle has two front wheels and one rear wheel. Rear wheel steering is sometimes used, although this increases the turning circle and can affect handling (the geometry is similar to a regular tricycle operating in reverse, but with a steering damper added). Some early pedal tricycles from
518-425: A delta trike can be quite close to the weight of a tadpole trike if they are both of a similar quality and similar materials are used. The Hase Kettwiesel Allround delta trike has an aluminium frame and weighs 39.4 lbs (17.9 kg). The Catrike Road tadpole trike has an aluminium frame and weighs 37.5 lbs (17 kg). The recumbent tadpole or reverse trike is a recumbent design with two steered wheels at
592-527: A geometry (also called center point steering) with the kingpin axis intersecting the ground directly ahead of the tire contact point, producing a normal amount of trail. This arrangement, elsewhere called "zero scrub radius" is used to mitigate the effects of one-sided braking on steering. While zero scrub can reduce steering feel and increase wandering it can also protect novices from spinning out and/or flipping. Tadpole trikes tend also to use Ackermann steering geometry, perhaps with both front brakes operated by
666-460: A paired rear triangle. This is known as the diamond frame . Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and fork of a bicycle and sometimes includes the headset and seat post . Frame builders will often produce the frame and fork together as a paired set. Besides the ubiquitous diamond frame, many different frame types have been developed for
740-457: A parking brake when stopped on a hill. Recumbent trikes often brake one wheel with each hand, allowing the rider to brake one side alone to pull the trike in that direction. On 1 July 2005, Sudhakar Yadav from India rode a tricycle in Hyderabad with a height of 12.67 metres (41.6 ft), a wheel diameter of 5.18 metres (17.0 ft) and length of 11.37 metres (37.3 ft). This tricycle
814-422: A quick and easy conversion. The advantages of a trike conversion set include lower cost compared with new hand built tricycles and the freedom to choose almost any donor bicycle frame. Tricycle conversion sets tend to be heavier than a high quality, hand built, sports, touring or racing tricycle. Conversion sets can give the would-be serious tricyclist a taste of triking before making the final decision to purchase

#1732787905979888-446: A range of manufacturers were available by 2000. The uncommon prone bike moves the cranks to the rear of the rider, resulting in a head-forward, chest-down riding position. A cross frame consists mainly of two tubes that form a cross: a seat tube from the bottom bracket to the saddle, and a backbone from the head tube to the rear hub. A truss frame uses additional tubes to form a truss . Examples include Humbers , Pedersens , and
962-405: A spinal cord injury. Tricycles have been constructed that tilt in the direction of a turn, as a bicycle does, to avoid rolling over without a wide axle track. Examples have included upright, recumbent, delta, and tadpole configurations. Tricycle conversion sets or kits convert a bicycle to an upright tricycle. Tricycle kit can remove the front wheel and mounts two wheels under the handlebars for
1036-446: A stronger stroking position. The trade-off is comfort. Touring and comfort bicycles tend to have more slack (less vertical) seat tube angle traditionally. This positions the rider more on the sit bones and takes weight off the wrists, arms and neck, and, for men, improves circulation to the urinary and reproductive areas. With a slacker angle, designers lengthen the chain stay so that the center of gravity (that would otherwise be farther to
1110-483: A vehicle that was powered by hand cranks. In 1789, two French inventors developed a three-wheeled vehicle, powered by pedals; they called it the tricycle. In 1818, British inventor Denis Johnson patented his approach to designing tricycles. In 1876, James Starley developed the Coventry Lever Tricycle, which used two small wheels on the right side and a large drive wheel on the left side; power
1184-481: A wide front and narrow rear offer superior aerodynamics to a delta trike configuration. Hand-crank trikes use a hand-operated crank, either as a sole source of power or a double drive with footpower from pedals and hand-power from the hand crank. The hand-power only trikes can be used by individuals who do not have the use of their legs due to a disability or an injury. They are made by companies including Greenspeed, Invacare, Quickie and Druzin. In case of paralysis of

The trike pictured is called the SUV (Sensible Utility Vehicle) and is produced by the company Organic Engines, which operates in Florida in the United States. It is a front wheel drive tricycle, articulated behind the driver seat, and has hydraulic double disc brakes and internal hub gears . The passenger
1332-465: Is achieved using a quick release lever. The seatpost must be inserted at least a certain length; this is marked with a minimum insertion mark . The seat tube also may have braze-on mounts for a bottle cage or front derailleur . The chain stays run parallel to the chain, connecting the bottom bracket shell (which holds the axis around which the pedals and cranks rotate) to the rear fork ends or dropouts. A shorter chain stay generally means that
1406-402: Is also known as a step-through frame or an open frame. Another style that accomplishes similar results is the mixte . In a cantilever bicycle frame the seat stays continue past the seat post and curve downwards to meet with the down tube. Cantilever frames are popular on the cruiser bicycle , the lowrider bicycle , and the wheelie bike . In many cantilever frames the only straight tubes are
1480-468: Is categorized as either a traditional geometry with a horizontal top tube, or a compact geometry with a sloping top tube. Traditional geometry road frames are often associated with more comfort and greater stability, and tend to have a longer wheelbase which contributes to these two aspects. Compact geometry allows the top of the head tube to be above the top of the seat tube, decreasing standover height, and thus increasing standover clearance and lowering
1554-466: Is electric golf cart-style vehicles, freight trikes are human-powered, so they do not have the maintenance required to keep batteries on golf carts charged up. Common uses include: A tricycle is a typical toy for children between the ages of eighteen months and five years before a balance bike . Compared to adult models, children's trikes are simpler, without brakes or gears, and often with crude front-drive. Child trikes can be unstable, particularly if

Diamond frame A bicycle frame is the main component of a bicycle , onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle , and consists of two triangles : a main triangle and
1702-404: Is most appropriate when used as part of a rear triangle subframe on a bicycle with independent rear suspension. A dual seat stay refers to seat stays which meet the front triangle of the bicycle at two separate points, usually side-by-side. Fastback seat stays meet the seat tube at the back instead of the sides of the tube. On most seat stays, a bridge or brace is typically used to connect
1776-413: Is protected from rain and sun with a canopy. Urban delivery trikes are designed and constructed for transporting large loads. These trikes include a cargo area consisting of a steel tube carrier, an open or enclosed box, a flat platform, or a large, heavy-duty wire basket. These are usually mounted over one or both wheels, low behind the front wheel, or between parallel wheels at either the front or rear of
1850-519: Is quite high compared to recumbent trikes. Because of this, non-tilting trikes are more prone to tipping over in corners and on uneven or sloping terrain. Conversely, the rider enjoys better visibility than on a recumbent because their head is higher. Recumbent trikes' advantages (over conventional trikes) include stability (through low centre of gravity ) and low aerodynamic drag . Disadvantages (compared to bicycles) include greater cost, weight, and width. The very low seat may make entry difficult, and on
1924-570: Is typically larger, unthreaded, and sometimes split. The chain stays, seat tube, and down tube all typically connect to the bottom bracket shell. There are a few traditional standard shell widths (68, 70 or 73 mm). Road bikes usually use 68 mm; Italian road bikes use 70 mm; Early model mountain bikes use 73 mm; later models (1995 and newer) use 68 mm more commonly. Some modern bicycles have shell widths of 83 or 100 mm and these are for specialised downhill mountain biking or snowbiking applications. The shell width influences
1998-451: The Q factor or tread of the bike. There are a few standard shell diameters (34.798 – 36 mm) with associated thread pitches (24 - 28 tpi). On some gearbox bicycles , the bottom bracket shell may be replaced by an integrated gearbox or a mounting location for a detachable gearbox. The length of the tubes, and the angles at which they are attached define a frame geometry . In comparing different frame geometries, designers often compare
2072-512: The wheelbase or track are insufficient. Some trikes have a push bar so adults can control the trike. Child trikes have frames made of metal, plastic, or wood. Children's trikes can have pedals directly driving the front wheels, allowing braking with the pedals, or they can use chain drive the rear wheels, often without a differential, so one rear wheel spins free. Children's trikes do not always have pneumatic tires , having instead wheels of solid rubber or hollow plastic. While this may add to
2146-470: The basic diamond frame design. The cycle types article describes additional variations. It is also possible to add couplers either during manufacturing or as a retrofit so that the frame can be disassembled into smaller pieces to facilitate packing and travel. The diamond frame consists of two triangles, a main triangle and a paired rear triangle. The main triangle consists of the head tube, top tube, down tube and seat tube. The rear triangle consists of
2220-415: The bicycle, several of which are still in common use today. In the diamond frame, the main "triangle" is not actually a triangle because it consists of four tubes: the head tube, top tube, down tube and seat tube. The rear triangle consists of the seat tube joined by paired chain stays and seat stays. The head tube contains the headset , the interface with the fork . The top tube connects the head tube to

The down tube connects the head tube to the bottom bracket shell. On racing bicycles and some mountain and hybrid bikes, the derailleur cables run along the down tube, or inside the down tube. On older racing bicycles, the shift levers were mounted on the down tube. On newer ones, they are mounted with

2368-426: The bike will accelerate faster and be easier to ride uphill, at least while the rider can avoid the front wheel losing contact with the ground. When the rear derailleur cable is routed partially along the down tube, it is also routed along the chain stay. Occasionally (principally on frames made since the late 1990s) mountings for disc brakes will be attached to the chain stays. There may be a small brace that connects
2442-514: The bottom bracket to the rear fork ends. The seat stays connect the top of the seat tube (often at or near the same point as the top tube) to the rear fork ends. Historically, bicycle frames designed for women had a top tube that connected in the middle of the seat tube instead of the top, resulting in a lower standover height . This was to allow the rider to dismount while wearing a skirt or dress . The design has since been used in unisex utility bikes to facilitate easy mounting and dismounting, and
2516-431: The brake levers on the handlebars. Bottle cage mounts are also on the down tube, usually on the top side, sometimes also on the bottom side. In addition to bottle cages, small air pumps may be fitted to these mounts as well. The seat tube contains the seatpost of the bike, which connects to the saddle. The saddle height is adjustable by changing how far the seatpost is inserted into the seat tube. On some bikes, this
2590-404: The center of gravity. Opinion is divided on the riding merits of the compact frame, but several manufacturers claim that a reduced range of sizes can fit most riders, and that it is easier to build a frame without a perfectly level top tube. Road bicycles for racing tend to have a steeper seat tube angle , measured from the horizontal plane. This positions the rider aerodynamically and arguably in
2664-399: The chain stays in front of the rear wheel and behind the bottom bracket shell, called a "chainstay bridge". Chain stays may be designed using tapered or untapered tubing. They may be relieved, ovalized, crimped, S-shaped, or elevated to allow additional clearance for the rear wheel, chain, crankarms, or the heel of the foot. The seat stays connect the top of the seat tube (often at or near

Designs such as recumbents or others which place
2812-415: The frames can be broken down into pieces for easier transport. Manufacturers of recumbent trikes include Greenspeed, WhizWheelz and Inspired Cycle Engineering. Most cycle rickshaws , used for carrying passengers for hire, are tricycles with one steering wheel in the front and two wheels in the back supporting a seating area for one or two passengers. Cycle rickshaws often have a parasol or canopy to protect
2886-434: The front (called tadpole ). The rider straddles the frame in both delta and tadpole configurations. Steering is through a handlebar directly connected to the front wheel via a conventional bicycle fork in delta, or via a form of Ackermann steering geometry in the case of the upright tadpole. All non-tilting trikes have stability issues and great care must be used when riding a non-tilting upright trike. The center of gravity
2960-434: The front and one driven wheel at the back, though one model has the front wheels driven while the rear wheel steers. Steering is either through a single handlebar linked with tie rods to the front wheels' stub axle assemblies (indirect) or with two handlebars (rather, two half-handlebars) each bolted to a steerer tube, usually through a bicycle-type headset and connected to a stub axle assembly (direct). A single tie rod connects
3034-456: The front wheel with a large handlebar (over seat steering). Some delta trikes can be stored upright by lifting the front wheel and resting the top of the seat on the ground. Delta trikes generally have higher seats and a tighter turning radius than tadpole trikes. The tight turning radius is useful if riding on trails with offset barriers, or navigating around closely placed obstacles. The higher seat makes mounting and dismounting easier. Even with

3108-415: The higher seat a delta trike can be quite stable provided most of the weight (including the rider) is shifted back towards the rear wheels. Many delta trikes place the seat too far forward and that takes weight off the two rear wheels and puts more weight onto the front wheel making the trike more unstable. The Hase Kettwiesel delta trike has an 18 in (460 mm) high seat that is placed to put most of
3182-439: The integrity of the traditional diamond frame may require additional gusseting tubes, alternative frame construction, or different materials for equivalent strength. ( See Road and triathlon bicycles for more information on geometries. ) Step-through frames usually have a top tube that slopes down steeply to allow the rider to mount and dismount the bicycle more easily. Alternative step-through designs may include leaving out
3256-404: The late 19th century used two wheels in tandem on one side and a larger driving wheel on the other. An in-line three-wheeled vehicle has two steered wheels, one at the front and the other in the middle or at the rear. Upright trikes resemble a two-wheeled bicycle, traditionally diamond frame , or open frame, but with either two widely spaced wheels at the back (called delta ) or two wheels at
3330-400: The left and right axle assemblies. The tadpole trike is often used by middle-aged or retiree-age former bicyclists who are tired of the associated pains from normal upright bikes. With its extremely low center of gravity, aerodynamic layout and light weight (for trikes), tadpoles are considered the highest performance trikes. Most velomobiles are built in a tadpole trike configuration since

The large leg muscles are activated by electrical impulses synchronized with the hand cranking movement. Recumbent tandem trikes allow two people to ride in a recumbent position with an extra-strong backbone frame to hold the extra weight. Some allow the "captain" (the rider who steers) and "stoker" (the rider who only pedals) to pedal at different speeds. They are often made with couplers so

In 2012, a variation of the traditional seat stay that bypasses the seat tube and connects further into the top tube was patented by Volagi Cycles . This frame element added length to
3552-402: The one pictured. A monocoque frame consists only of a hollow shell with no internal structure. Folding bicycle frames are characterized by the ability to fold into a compact shape for transportation or storage. Penny-farthing frames are characterized by a large front wheel and a small rear wheel. Tandem and sociable frames support multiple riders. There are many variations on

It is usually threaded, often left-hand threaded on the right (drive) side of the bike to prevent loosening by fretting induced precession , and right-hand threaded on the left (non-drive) side. There are many variations, such as an eccentric bottom bracket, which allows for adjustment in tension of the bicycle's chain. It

These vehicles are widely used in South Asia and Southeast Asia, where rickshaw driving provides essential employment for recent immigrants from rural areas, generally impoverished men. In the 1990s and first decade of the 21st century, rickshaws became increasingly popular in big cities in Britain, Europe and the United States, where they provide urban transportation, novelty rides, and serve as advertising media.

#17327879059793848-401: The rider makes a pair of front wheels change directions by shifting the center of weight and moves forward by rotating the rear wheel. The hand and foot trike can be also converted into a manual tricycle designed to be driven with both hands and both feet. There are also new hybrids between a handcycle, a recumbent bike and a tricycle, these bikes make it even possible to cycle with legs despite
3922-443: The road is the principal difficulty to be overcome once basic tricycle handling is mastered. Recumbent trikes are less affected by camber and, depending on track width and riding position, capable of very fast cornering. Some trikes are tilting three-wheelers, which lean into corners much as bicycles do. In the case of delta tricycles, the drive is often to just one of the rear wheels, though in some cases both wheels are driven through
3996-433: The road they may be less visible to other traffic. A recumbent delta is similar to an upright, with two wheels at the back and one at the front, but has a recumbent layout in which the rider is seated in a chair-like seat. One or both rear wheels can be driven, while the front is used for steering (the usual layout). Steering is either through a linkage, with the handlebars under the seat (under seat steering) or directly to

When the rear derailleur cable is routed partially along the top tube, it is also usually routed along the seat stay. Many alternatives to the traditional seat stay design have been introduced over the years. A style of seat stay that extends forward of
4144-541: The seat tube and the head tube. The recumbent bicycle moves the cranks to a position forward of the rider instead of underneath, generally improving the slipstream around the rider without the characteristic sharp bend at the waist used by racers of diamond-frame bicycles. Banned from bicycle racing in France in 1934 to avoid rendering diamond-frame bicycles obsolete in racing, manufacturing of recumbent bicycles remained depressed for another half century, but many models from
4218-434: The seat tube angle, head tube angle, (virtual) top tube length, and seat tube length. To complete the specification of a bicycle for use, the rider adjusts the relative positions of the saddle, pedals and handlebars: The geometry of the frame depends on the intended use. For instance, a road bicycle will place the handlebars in a lower and further position relative to the saddle giving a more crouched riding position; whereas
4292-435: The seat tube at the top. The top tube may be positioned horizontally (parallel to the ground), or it may slope downwards towards the seat tube for additional stand-over clearance. The down tube connects the head tube to the bottom bracket shell. The rear triangle connects to the rear fork ends , where the rear wheel is attached. It consists of the seat tube and paired chain stays and seat stays. The chain stays run connecting
4366-415: The seat tube, and paired chain stays and seat stays. The head tube contains the headset, the bearings for the fork via its steerer tube . In an integrated headset, cartridge bearings interface directly with the surface on the inside of the head tube, on non-integrated headsets the bearings (in a cartridge or not) interface with "cups" pressed into the head tube. The top tube , or cross-bar , connects
4440-461: The seat tube, below the rear end of the top tube and connects to the top tube in front of the seat tube, creating a small triangle, is called a Hellenic stay after the British frame builder Fred Hellens, who introduced them in 1923. Hellenic seat stays add aesthetic appeal at the expense of added weight. This style of seat stay was popularized again in the late 20th century by GT Bicycles (under
4514-399: The stays above the rear wheel and below the connection with the seat tube. Besides providing lateral rigidity, this bridge provides a mounting point for rear brakes, fenders, and racks. The seat stays themselves may also be fitted with brake mounts. Brake mounts are often absent from fixed-gear or track bike seat stays.

While the KMX Kart stunt trike with this setup allows the rear brake to be operated separately, letting the rider do "bootlegger turns", the standard setup for most trikes has the front brake for each side operated by each hand. The center-of-mass of most tadpole trikes is close to the front wheels, making the rear brake less useful. The rear brake may instead be connected to a latching brake lever for use as

Freight trikes are also designed for indoor use in large warehouses or industrial plants. The advantage of using freight trikes rather than a motor vehicle is that there is no exhaust, which means that the trike can be used inside warehouses. While another option
4736-415: The top of the head tube to the top of the seat tube. In a traditional-geometry diamond frame, the top tube is horizontal (parallel to the ground). In a compact-geometry frame, the top tube is normally sloped downward toward the seat tube for additional standover clearance. In a mountain bike frame, the top tube is almost always sloped downward toward the seat tube. Radically sloped top tubes that compromise
4810-417: The top tube out completely, as in monocoque mainframe designs using a separated or hinged seat tube, and twin top tubes that continue to the rear fork ends as with the mixte frame. These alternatives to the diamond frame provide greater versatility, though at the expense of added weight to achieve equivalent strength and rigidity. Control cables are routed along mounts on the top tube, or sometimes inside
4884-410: The top tube. Most commonly, this includes the cable for the rear brake, but some mountain bikes and hybrid bicycles also route the front and rear derailleur cables along the top tube. Inside routing, once only present in the highest price ranges, protects the cables from damage and dirt, which can e.g. make gear shifting unreliable. The space between the top tube and the rider's groin while straddling

Another common seat stay variant is the wishbone , single seat stay , or mono stay , which joins the stays together just above the rear wheel into a monotube that is joined to the seat tube. A wishbone design adds vertical rigidity without increasing lateral stiffness, generally an undesirable trait for bicycles with unsuspended rear wheels. The wishbone design
