GBNpro, a bug-screen bike helmet manufacturer, has announced that a recent electric kit upgrade test has been successful. In January of this year the company commissioned two technicians from South Shor Cyclery in Wisconsin to convert a Rans Screamer tandem recumbent bicycle into a pedal-assist model by installing a BionX kit on the vehicle.
The BionX 350 watt electric hub motor is powered by a 37 volt lithium-ion battery, giving the tandem bike a top speed of 21 miles per hour. The company says that the electric bicycle can go 11 miles per hour while carrying two adults, against the wind, up-hill without any pedaling necessary.
While the battery can be charged by plugging-in at home, which takes up to three hours to reach full capacity, it also features a regenerative braking system and and optional four level power generation system while pedaling. So far, the company has only used the new device around a dozen times, and notes that a range of 15 miles in electric-only mode depleted the battery to about 30% capacity.
