Gruber Assist: A Little Help?

You’ve got the bike hanging but you haven’t got the legs anymore to pedal your way up even on the smallest of hills. What you need is an invisible assistant, something that can magically push your way up the slope. The Gruber Assist is a small, tubular 200-watt motor that fits into your bike’s seat tube and gives you that much needed power at the push of a button. This means that you won’t need to buy a whole new bike, just retrofit your existing ones into an electric bike. As long as you have a flat seat tube and it’s 31.6-mm across, the Gruber motor will fit in. Powered by batteries inside the provided saddle, you can enjoy up to 1.5 hours of assisted pedaling, depending on how crazy you are with the boost button. ~$2,500.
