This Kickstarter idea is one very clean electric conversion kit for just about any conventional bike. The Rubbee allows the rider to switch between a regular bicycle and an electric in just a matter of seconds. You don’t have to carry a battery pack and the Rubbee can be shared between bikes.

The inventor is claiming that Rubbee had a 15 mile range with a top speed of 15 miles per hour. The unit is claimed to weigh 14 pounds and puts out a peak power of 800 watts. They also claim the battery can go from dead to fully-charged in 2 hours.

THE COMPONENTS:

Cast friction wheel: The friction wheel is where the rubber meets the road, or meets the rubber should we say. We cast these rollers from a special polyurethane formula we’ve developed for this application. It provides maximum grip while keeping Your bicycle’s tire from wearing off too much. This is where we make sure the power is transferred via rubbing and not grinding. And that’s where the name comes from – Rubbee. The muscle of Rubbee – electric motor electronically limited to allows peaks of power up to 800W is integrated inside this roller. With the help of some ultra-cool mechanical parts, of course.

 Multifunction power button: The power button functions as an ON/OFF switch and as a battery level indicator. Integrated blue-colored LED blinks corresponding to the state of charge of the battery pack. The faster it blinks – the less power You have left. It also shows the status of the batteries when the Rubbee is being charged.

 Integrated suppression system: It makes sure Rubbee always provides a constant force on the tire of the bicycle thus allowing minimum slip even in wet conditions. This feature also enables Rubbee to be used even on the bicycles with rear wheel suspension where the geometry of the bicycle is always changing. Suppression system only engages when the fixation pin is removed. That means that You can ride around with Rubbee on Your bicycle even without it touching the tire. This feature comes in handy when Rubbee “gets out of breath”.

Battery pack: Rubbee has an integrated battery pack custom made just for this product. It delivers extremely high currents to power You up the hills. The lifespan of this pack is over 2000 cycles – this will make sure You can recharge Rubbee every single day for 5 years without loosing any range. We also integrated a custom made electronic battery management system just to make sure the battery pack delivers what is expected.

Multipurpose connector: Rubbee has only one electronic plug. It uses the same port to connect the throttle / PAS sensor and to connect the charger. Ingenuity in simplicity.

 Waterproof construction: Versatility is the word for Rubbee. And that includes weather conditions. Rubbee can be used even when it is raining outside because all electronics and the drive unit itself are waterproof. Our suppression system and custom cast roller makes sure that there is minimum power loss even when the tire gets all wet and muddy.

Rear LED light: Safety first! We care about the riders and understand the need to be visible at night. Rubbee has an integrated super-bright LED rear light which shines bright red. It turns on automatically when You turn Rubbee on. And it also looks cool.
