Twike
The Twike (a contraction of "TWin" and "bIKE") is a human-electric hybrid vehicle (HEHV) designed to carry two passengers and cargo. Basically a velomobile with an electrical hybrid engine, it can be driven in electric-only mode or electric + pedal power mode. Pedaling warms the user, making electric heating in winter unnecessary, extends the range of the vehicle but does not substantially add to the vehicle's top speed. Only two pretty sporty and engaged riders can pedal the vehicle slowly without the use of the electric motor if surface is smooth and horizontal or somewhat declined.
Constructed of lightweight materials such as aluminium (frame) and plastic (shell), the 246 kg (542 lb) (unladen, varying with battery weight) tricycle vehicle used in first versions NiCd-batteries, later Lithium-Mangan, LiFePO4 and LiIon. Typically ranges ranges reach from 50 to 300 km depending on battery size, type, status on one side and speed and altitude profile and load on the other. Energy is reclaimed while driving through regenerative braking, and load is removed from the electric system by use of the pedalling system which transfers its input directly to the drivetrain (i.e., both systems operate in parallel, not in series).
==Description==
The Twike is a three-wheeled two seater. The two rear wheels are direct-driven via a differential gear by onemotor - and optionally additionally by 2 pairs of pedals in the case of the model "active". Twike is steered by joystick - for the right hand of the left-side seated pilot - via cables and has pedal brakes. The vehicle can reach speeds of up to 85 kilometers per hour (53 mph), using 7.4 kWh per 100 km. At 50 km/h it can drive up to 80 km.
