Schlumpf Speed Drive. A Schlumpf Drive is a two-speed planetary gear assembly for use on bicycles and unicycles. It is distinct from other bicycle planetary gear assemblies in that it is located behind the chainring rather than in the rear hub. A push-button on each side of the axle allows the rider to switch between high and low ratios.
The Trikke (/ ˈ t r aɪ k / tr-EYE-k; also known as a wiggle scooter, scissor scooter, carver scooter, Y scooter, or V scooter) is a chainless, pedalless, personal vehicle with a three-wheel frame. The rider stands on two foot platforms above the two rear wheels and steers the vehicle with handlebars attached to the lone front wheel.
Rear-wheel steering tends to be directionally unstable, and so the vast majority of trikes employ front-wheel steering. [5] A notable exception is the Toyota i-Road . [ 6 ] In the case of two wheel steering, some accommodation is usually made to account for the different radii of their paths, such as Ackermann steering geometry .
A chain drive and rear derailleur gear change, the most popular system in use today A shaft-drive with crankset and rear gear hub. Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels.
Most recumbents have the cranks attached to a boom fixed to the frame, with a long drive chain for rear wheel drive. However, due to the proximity of the crank to the front wheel, front wheel drive (FWD) can be an option, and it allows for a much shorter chain. One style requires the chain to twist slightly to allow for steering. [9]
When both power sources are used the MP3 can run for a maximum of 25 minutes, with performance equivalent to a 250 cc scooter. [3] When powered solely by the petrol engine the MP3 is slower than other 125 cm 3 machines due to its weight: 249 kg (549 lb) compared with 208 kg (459 lb) for the petrol-only model.
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 the wheelbase or track are insufficient. [22] Some trikes have a push bar so adults can control the trike. [22] Child trikes have frames made of metal, plastic, or wood.
As of December 2021, Trident's product lineup includes mostly tadpole trikes, [3] with two front wheels and one rear wheel. Despite their trademarked motto "3 wheels good... 2 wheels bad!", [4] they do offer the T.W.I.G as a 2 wheel recumbent. Some models are available with electric (E) assist options.
