I gather the Gruber is noisy in operation, not stealthy enough that you could get away with using it in competition.

And think of all the photos taken of Fabian and his bike during those races, by fans and pros, still and video. Even a very discreet button would be discovered.

I'd still like one though . . .

The thing with e-bikes is that they can be easily modified to go 25-30 mph on electric alone, and people moving at that speed don't mix well with regular cyclists pedaling 15 mph on narrow bike lanes. The technology is new enough that there isn't a clear code of conduct. When should an e-bike rider be in the bike lane versus in the normal traffic lane? How can you tell if an e-bike complies with max power limits if the motors look the same at different power levels? So far this hasn't been a problem in my experience, I seldom see any e-bikes on the road. But it will be.

I'm seeing a whole lot more of electrics. Not sure if municipalities regulate e-bikes and I have no problem if they use a bike path or trail. Surely they are improving and lighter weight.



A look into the future with the tiny Gruber bevel drive electric motor set into a seat tube / bottom bracket. Priced at a whopping $2,400.. just for the parts and has to be custom installed. Cylinder type battery NiCad packs like the ones used in a Paslode nailer make the whole package even more stealth.

Remember the rumor Fabian Cancellara was using a secret motor to assist him on both his victories at the Tour of Flanders and Paris-Roubaix?
