Turn Any Bike Into An Electric Bike, No Installation Necessary


Rubbee via Kickstarter

Hook Rubbee on to the back of your pedal-powered bicycle, and let the machine do all the work.

So you want to bike, but, ugh, pedaling, right? Get an electric bike instead! And, if you already shelled out the dough for a regular bike, you can just invest in this Kickstarter for Rubbee, an attachable engine that pedals your bike for you.

Electric-bike conversion kits aren’t hard to find, but this looks like an especially easy (and stylish) way of transitioning: the machine just hooks on to the back of your seat and one end rests on the back wheel. An electric-powered wheel on the Rubbee spins against the bike wheel, creating friction and spinning the bike wheel. Spinning bike wheels, you perhaps are aware, is how people bike. Rubbee can get the bike moving at up to 15 mph for up to 15 miles. It weighs 14 pounds and takes about two hours to charge.

Rubbee’s on Kickstarter right now, and the creators are shipping them off as reward for donating 799 pounds, or a little more than $1,200. You can get an electric bike for much cheaper than that, but if there’s an analog bike you’re really attached to, or you’re not a fan of how most electric bikes are rigged, maybe it’s worth it for an easy upgrade.
