An entrepreneur is looking for $100K on Kickstarter to fund production of Shareroller, an ingenious, portable, snap-on electric motor for city-share bikes, like those in NYC, London, Toronto, Montreal, DC, Minneapolis, etc. The motor -- which weighs about 7 lbs and is the size of a ream of printer-paper -- clips onto the triangular docking prong on the front of the bike, and uses a retractable friction-wheel to impart energy to the bike. It also works on scooters and personal bikes, though these require a special mount.
Shareroller sports a big, powerful battery, and the inventor is alive to the possibilities here. It includes USB charge-ports for your phone and other devices, so you can charge while you ride. It also has a set of high-powered headlights. The 750W, 1hp motor has a maximum range of 12 miles at 18mph (it will go farther is you help by pedalling).
The device is reportedly ready for production. $1000 gets you one from the initial run. $1300 is full list price (more if you opt for the range-extending extra battery). They'll sell you one of their functional, pre-production prototypes for $2000, shipping as soon as the Kickstarter is fulfilled, and replaced with a production model when they are available.
The creator has a fairly impressive track record of making and shipping stuff, though, as with all Kickstarters, there is no guarantee that your money will get you anything.
I like the exercise I get from pedalling around on short-hire bikes in London. But I also like the idea of getting all the way across town in the middle of summer and arriving without being drenched in sweat. Read the rest
