The Gruber Assist electric bike  

DVice has a post on an interesting idea for helping cyclists along with some electric support - Gruber Assist electric bike: Only your cycle mechanic will know for sure.

Do you see any sign of an electric bicycle when you look at those pedals pictured above? That's the remarkable stealth of Gruber Assist, a $2,473 kit for any bicycle that gives you electric motor-assisted cycling on the sly. You can either retrofit an existing bike or get an entirely new bicycle from Gruber with the motor installed.

The pedal is just the tip of the iceberg — the motor and electronics are hidden inside the seat tube with the battery tucked away in a saddlebag, and it's controlled with a handlebar-mounted switch. Gruber Assist's 200-watt motor will deliver 100 watts of power to the rear wheels, and runs for between 45 minutes and 1.5 hours on a charge, depending on how much you pedal.

Electric bikes are so much fun, but they can look a little clunky. This is the most discreet electric bike configuration we've seen yet, because hey, it's almost invisible. It's so stealthy, an unscrupulous cyclist could almost slip one of these into a racing bike, unnoticed. Almost.
