Innvelo Two

Emobility vehicles - electric bikes and scooters

The new generation of e-bicycles and e-scooters shown at this year's Hannover Messe exhibition are aiming to take powered urban mobility to new levels of drive versatility and environmental sensitivity. Not only are they green and groovy, but find an open power point and you can juice 'em up for free!

1 Developed in the context of a ZIM NEMO network (support programme of the German government) and cared for at the ICM e.V. - Institute of Mechanical and Plant Engineering in Chemnitz - Innvelo Two is approved for the use on public roads with a top speed of 45km/h. Besides this model, a 'throttled version' with a top speed of around 40km/h is planned which enables the use of inner-city cycling tracks. The lightweight (approximately 30kg) electric scooter has a range of about 30-40km in 'normal' driving conditions and on plain level. With the supplied charger the innovative lithium-polymer battery (10h) recharges in about 6-7 hours. Hydraulic disc brakes provide the necessary security.

2 With a top speed under motor power of nearly 25km/h (the max for pedal-assist e-bicycles under European law), Ultra Motor - maker of the A2B range - is reluctant to specify the bike's range, saying it depends too much on terrain and assist level, and traffic type'and rider weight, but typically its makers say to expect around 64km on one battery charge, based on a 90kg rider heft. The A2B Metro has an option to add a second battery (on the downtube or on the rear rack), which doubles its range. Recharging is as "easy as charging a mobile phone or laptop", Ultra Motor says. Full charge takes between three to four hours from flat to full.

3 Developed for use in businesses like postal services and by trades- persons, the three-model GOVECS GO! S-Series range includes the GO! S1.2, GO! S2.4, and GO! S3.4 models with top speeds of 45 km/h (S1.2, S2.4) to 80 km/h (S3.4). Hydraulic disc brakes in the higher-end T-Series models also make 'regenerative braking' possible, which claims to return energy. Lithium-polymer batteries with Panasonic cells and diagnostic software provide a range of at least 50 km, and in the case of the GO! T2.4, a claimed top range of 100km. GOVECS scooters can be recharged at household sockets using the integrated charger to a 220v or 110v supply. The S2.4 has a torque of 5.4Nm; top GOVECS models claim a torque of 114Nm.

4 The Vetrix VX-2 reckons itself to offer the electric equivalent of a 50cc internal combustion engine scooter offering speeds up to 45km/h, and a factor-dependent range of 64-to-88km. The VX-2 comes with the patented Vectrix Multi-Function Throttle s standard which provides regenerative braking and slow-speed reverse. Each VX-2 comes with a 48V/20A battery charger that plugs into a standard 110V/220V outlet and features a charge time of around 3.5-5 hours. The VX-2's lower profile and lighter weight (steel-tube chassis construction) have won plaudits from reviewers: one called the scooter "a clever combination of high- and low-tech, high-end and low-end, designed to provide a practical transportation solution to short-range intra-urban commuters".

5 The Solexity is ideal for smart urban transport and it can reach a variable electrical assistance speed of up to 25km/h in two modes (sport and low), and has autonomy of up to 60km depending on the engine's power mode, the driver weight, the type of road, tyre pressure and wind direction. The LCD display on the handlebar provides information on the speed, distance covered, riding range, current energy consumption and assistance mode. Features Shimano front disc brake, Shimano roller rear brake, and removable 36V/9 Ah Leclanch' rechargeable battery. Available in four colours: black, grey, fawn and red.

6 The e-Tricycle is based on the 'hop-on, hop-off' concept, meaning it was created for uses like exhibition touring, city tours, factories and warehouses, plus for getting round airports and golf courses. The flexibility is provided for short distances and has a lithium-Ion battery 36V/25Ah with a four-hour charging time. The maximum speed is 20km/h, it has a range of 30km with a motor performance of 500W. The steel frame weighs 40kg and the aluminium option weighs 18kg; the vehicle's dimensions are 148 x 74 x 124cm.

7 The inspiration behind the Exo e-bike's frame is the Japanese art of origami: the sculptures made of folded paper are, its makers say, seen in the design. The 45kg bike is made from aluminium and includes a lithium-Ion battery 48V/30Ah with has a 7-8 hour charging time; this enables the bike to drive 50 to 60km every charge. The ideal passenger weight is 90kg to drive at a max speed of 45km/h.

8 Designed as a trendy and foldable 'funsport' product to be used as a transport device in an industrial context, or as a vehicle suited for daily use, maker of the eMove sees the vehicle as a rival to the Segway. The maximum speed is 30km/h and its motor performance ranges from 350-500W. The separation of the wheel-hub-energy-unit and the standing surface for the driver is connected through a cardan joint to enable a sports feel drive.

9Scuddy is available in two different versions: the 35km/h sport-version, which drives up to 30km, and the 20km/h city-version, which drives up'to 40km. Both have an eco-to-performance energy mode. A three-wheeled foldable electric scooter, Scuddy weighs 23kg, and its components include a trolley, 10Ah/51.2V lithium iron phosphate battery with a four-hour charge time, a brushless DC motor, and'a recuperation brake on the rear wheel'and hydraulic disc brakes on both front wheels.

10 Not as new as other contenders in the e-bike market, Elmoto has held its own against newcomers in the e-mobility market. Once described as offering "the convenient practicality of a bicycle and some of the power and comfort of a small scooter", although its maker prefers comparison with a motorbike. The 47kg Elmoto offers 45km/h top speed with 50Nm torque, typical range of 65km, with an engine that turns off when the brake is applied. Total recommended load is 150kg.
