Gruber Assist, according to Cycling News, the motor is inserted down the seat tube of pro tour riders and interacts with a standard bottom bracket axel via a bevel gear unit. It is practically invisible but weighs a ton, although the model displayed on its website has an external on/off switch plus a battery pack that is mounted in a saddle bag. The total weight of all of the components is 1900 grams, and can provide 100 watts of power.
If we all start showing up to the start line with heavy bikes and/or large saddle bags then we will be packing a motor!
From the actual website - GRUBER Assist- a high-quality tuning product for your bicycle:
GRUBER Assist is an ultra-light drive for mountain bikes, trekking cycles and tour cycles, suitable for later installation. The skilfully conceived Gruber motor is invisibly built into the bicycle (seat tube with an inner diameter of 31.6mm required) and scores especially highly on account of its light weight (900 g).
A touch of the Turbo button on the handlebar – and the burning sensation in your thighs disappears – the healthy perspiration, however, remains. The auxiliary drive, with its 200 watt of additional power, promises a performance increase of up to 100% – for min. 45 minutes at full load. When the drive is switched off, you continue cycling as normal. GRUBER Assist guarantees pleasurable cycling without a red face!
