Okay, not a vast amount of hidden power, 200 watts is the claimed amount, but it should be enough to help you up those hills.
The Gruber Assist. An electric power assist motor for your bike that lives in the seat tube and only weighs 900g (the battery goes in a wedepack under your saddle and adds a further 1Kg. It produces a claimed 200 watts and the battery gives an hour and a half of continuous use. The idea is that you only turn it on when you have to go up hill.
To fit one you’ll need a bike that’s fitted with a Shimano Hollowtech II chainset and with a 31.6mm seat tube (or greater), so we’re talking mountain bikes, trekking bikes, hybrids and some tourers. Oh, and you’ll need a big pile of cash too as these things cost over $2,000 dollars.
And of course the whole thing is cheating!

This vid gives more of an idea of what the ‘hidden hand’ is like in action… guess which rider has the Gruber Assist
