Bicycling is great exercise but sometimes you need a little extra push to get up those hills or to make it back home without giving yourself a heart attack (Lance Armstrong not included). With Gruber Assist (Gruber marketing people- send me $200 and I’ll come up with a catchier name for you!) attaches to the frame of your existing bicycle and provides an electric motor with 200 watts of power for up to 1.5 hours of riding time. The device is completely hidden INSIDE your seat post and is very light. It’s a bit pricey at $2400 but it’s still a cool toy for cyclists.
