Gruber Assist auxiliary drive turns nearly any bicycle into an ebike

Bicycles can be a great way to reduce fuel consumption. They are efficient, relatively inexpensive, easy to store and care for and are often a fun way to score a little exercise while also getting you where you need to go. Of course, it's not always practical to pedal, which is one big reason that electric bikes are gaining in popularity so quickly.

What if you've already got a good bike but would like to add a bit of electric assistance? Enter the Gruber Assist, a new retrofit ebike system that fits into any standard 31.6mm seatpost. A small electric motor slides into the seat tube and engages with a geared bottom bracket to add 200 Watts of assistance when needed.

The entire Gruber Assist system weighs just 900 grams including a nickel metal hydride battery pack with enough juice to provide up to 1.5 hours of assisted pedaling. An even lighter lithium ion pack is also available. The price may be a little steep at £1649 (about $2,473 in U.S. funds), but the technology is undeniably cool.
