A Kickstarter campaign is underway for a new method of converting your standard bike into an electric bicycle. The Rubbee is an attachment placed on the seat and back tire that will allow cyclers to travel around town without actually needing to pedal; as usual for common electric bicycles and convertors. However, Rubbee attempts to provide this service with a much more convenient and consumer friendly approach.
The Rubbee, first and foremost, is lightweight. Weighing in at around 6 kilos, or about 14 pounds, Rubbee does the job at a manageable weight. Rubbee is also significantly easier to install on bikes than other conversion kits. All you have to do is clamp the device to the seat, remove the fixation pin, connect it to the supplied throttle attached to the handlebars and turn it on. You’re set to ride around on your freshly converted electric bike for up to 15 miles at speeds up to 15 miles per hour.
The Rubbee works by using friction to rub against the back tire, turning it as it would if you were to pedal. The company behind Rubbee promises that the device will not grind into the tire preserving the tire’s lifespan. The company even states that they developed, “a special polyurethane formula” just for this sake.
The Rubbee recharges in about 2 hours and fits on most standard bicycles, tires and frames. No clear price has been established for the Rubbee as of now but its Kickstarter page lists a pledge reward of the device itself, along with other prizes, for £800.
