Ultra Motor Ltd, which manufactures and sells the A2B electric bike, has filed for the UK equivalent of bankruptcy reports Bike EU.
Ultra Motor was founded in 2003 to develop drive-trains and power electronics technologies for electric vehicles. In September 2008, Ultra Motor launched its first product line in the United States – the A2B brand.
Panasonic announced a new, ultra low step through ebike with 20″ wheels targeted for Japan’s elderly population.
Japanese electronics giant Kyocera announced a turn-key ebike charging station powered with photovoltaic cells.
Privately owned Robert Bosch GmbH — the largest automotive component supplier in the world — sees the winds of change and has started an eBike subsidiary: Bosch Powertain Systems eBike.
Sanyo has combined three cool things I like into one, easy to use package: solar power generation, bike share, and electric bikes. This is so amazing I think my head will explode.
Sanyo Eneloop electric assist bicycle: “Ene + Loop” describes “energy looping” features: regenerative charging, pedal assist bicycle.
Sanyo launched their Eneloop ebike to the North American market today at Interbike. The Eneloop bike is expected to be available through independent bicycle dealers and specialty retailers throughout the United States beginning in November 2009, with a suggested retail price starting at $2,299.
Regenerative battery charging can be done by braking and by going downhill to extend the bike’s range.
The eneloop bike is a 26-inch, three-speed regenerative, pedal-assist hybrid electric bicycle. As such, riders can propel the eneloop bike under their own power or can engage the bike’s motor and electrical system to pedal in one of three assist modes – standard, power-up or auto – where the front hub-based motor helps the bicycle and rider travel forward.
As with similar ebikes, power and mode are selected from a handlebar mounted panel switch. The Sanyo eneloop is somewhat unique in that the bike lights are integrated with the other electronics of the bike; other ebikes tend to have lighting as a separate system if they’re included at all.
As with most other ebikes, the power assist comes from a hub motor. The motor, mounted in the front hub, is a 250 watt DC brushless motor.
Sanyo claims the Eneloop bike motor can provide as much as twice the effort as you put into pedaling, while previous pedal assist bikes provide about a 1:1 assist ratio. A torque sensor at the rear wheel senses the pedal power and adjusts the powered wheel output accordingly.
Some features of the eneloop bicycle:
- 25.9 volt/5.7 Ampere-hour(Ah) lithium-ion battery
- Charge time ~ 3.5 hours
- Total bike weight ~ 50 pounds (about typical of hybrid ebikes)
- Taillight brake lamp – High-intensity, flashing LED tail lamp that operates when the headlight is turned on and flashes faster when braking
- Handlebar panel switch
- Low frame and saddle design to allow easy step-through and mounting
- Seat that accommodates 26-inch framing
- Neatly-designed frame with internal cabling
Expected riding distances:
- Up to 17 miles in Standard Mode – no charging while riding (with the motor engaged)
- Up to 20 miles in Power-Up Mode – regenerative charging via braking only
- Up to 40 miles in Auto Mode – full regenerative charging
