September 5, 201411 yr I'll have what he's having...... http://www.theguardian.com/sport/2014/sep/04/ryder-hesjedal-motorised-bike-vuelta-espana
September 5, 201411 yr There's no such thing yet as a silent enough but still useful in-frame motor, and checks have found nothing when such accusations have been made. Given how low powered the motor would have to be for sufficient silence to get away with it, and the restricted amount of battery capacity that could be hidden, it could only be an occasional help anyway on these long road stages. So at all times when the motor was out of use there would be a weight penalty disadvantage offsetting the tiny gain. So I can't see it happening, unlike doping it's too difficult to conceal from the sport's authorities anyway. .
September 5, 201411 yr This is such a joke, and you guys should know better than most. If its crank driven... the cranks need to be going around to drive the rear wheel!!! so in order for this to be working it has to be a hub drive, with a button throttle that the bike happens to have landed on, and then you have to get a meaningful motor into one of the tiny road racing hubs they use. Plus he's doing about 50kph on a descent so why would the motor even be on?

Are you sure about that? Jump to 1:20.
September 5, 201411 yr Wouldn't want to be hit on the head when he discards a water bottle - it's probably got a 2kg battery inside.
September 7, 201411 yr I wasn't suggesting its not impossible to hide a motor. I was suggesting its I thought it was impossible for a crank drive motor to drive the rear wheel if the cranks aren't turning. I've ridden and playing with a lot of this "hidden" systems, they are very funky, but they drive the BB axle. So if the cranks are stopped because the bike is on the ground, there is no way they will keep powering the rear wheel. This is the one we'd been playing with for quite a while. http://www.vivax-assist.com/en/unternehmen/index.php
