Hybrid bicycle

9 posts in this topic

Just an idea, not sure how practical it is. Those of you more technical than me may let me know about details and what you think.

Basically I was thinking about the mechanics of a hybrid and how it stores braking energy for later use. This idea does not have to necessarily be connected to a gasoline-run system.

Think about a bicycle with a small electric motor integrated either into the bottom bracket (where the cranks attach) or into the rear wheel hub. A battery could be mounted on a rear rack, over the rear tire. The brakes could operate this in reverse to generate power (as in a hybrid car). You could then have some kind of throttle for a little electric boost to help you up hills.

There are people who will pay $3k for a decent dual-suspension mountain bike frame. I wonder if there are people who would pay the required price for a setup like this?

sounds like more of a novelty item than anything. The advantages of a hybrid system go down as vehicle mass goes down, and a bicycle doesn't exactly have much mass.

I thought a hybrid bicycle was ridden by a guy who was shocked when he slowed down and accelerated when he farted. :lol:

Instead of being like a 10-speed, does it come with a CVT? :AH-HA_wink:

Speaking of which... has anybody else seen these automatic bicycles??? I saw an informercial late one night for one of these things. Essentially your derailleur (gear changer) senses the hub speed and changes the gears for you. It was all mechanical and not sensor based, looked pretty interesting.

i know there is a bike with a shaft driven wheel, and an 2wd version too. it uses an automatic gear change... pretty sure i heard about a near cvt bike too, chain driven.
