There are times when an electric bike can come in handy, but for those who prefer simple pedal power buying an electric bike might seem a waste. Not only is there the added cost, but also the weight. However, the Rubbee could be just the thing.
This add on gizmo is being developed through a Kickstarter project, can turn (almost) any regular bike into an electric bike. This unique conversion kit features an integrated clamp mechanism that can be mounted on a bike in just a few seconds, while the innovative drive motor with an internal battery can help propel the bike for more than 25 miles without pedaling. Unlike other kits that can add as much as 15kg to the bike, this one weighs just 6.5kg (14 pounds), and it can fully recharge in just two hours.
