You wouldn't want to use it ALL race, in the peloton on the flat you could just cruise along with it. You might even be able to have it reverse direction and charge it's own battery back up.

Then you could use it for a sexually explicit spooge of speed on the last few hundred meters of a climb for every climb of the day :0

Tubular LiPo batteries would be easily hidden in a hand laid up carbon frame. EDIT: these batteries are good for about 150 Watt hours per kg currently. Also there is no need for them to make the silly distinctive zizzing noise the Gruber's make either.

The magnetic fields and magnetic material in the assist motor would be ultra easily detected, eg a rare earth magnet held to the bottom of the seat tube - if the magnet 'wants in' there is something sus lurking in there - probably a motor.

Should it? Hydraulic controls are fair enough, they just transmit the rider's effort very efficiantly, but an electric rear mech is reducung the rider's workload.

Minimal, but you are right, they are using prestored energy that is not their own in powering a part of their bike.

A rough calculation gave me 40 odd 26650 LiPo batteries (to get 400Wh @ 12V). The batteries are 65mm long, so that's 2.6m of batteries! These guys are riding bikes with 560-600mm top tubes? Similar length for the downtube, that's 1.2m of space! They would have to have the balance stored up their jacksie!

have you noticed the trend towards wide tubing, particularly on carbon frames?

The weight difference would not be that bad if they hid the battery up the riders butt :crazy:


The prongs pointing up on the saddle might be a bit obvious however?!?!

edit: and pedal standing would lead to a loss of power...

A la the Lancia rally team, where they felt the need to change the "fire extinguisher" bottles every service. Only thing is they were plumbed into the engine and contained Nitrous!
