Converting a Road Bike???

Everyone seems to be doing mountain bikes... That's nice, but I have a road bike and 15 mile commute. I like the exercise, but.... Man do I wish I had some help.

Any options for me?

Bionx systems work well on road bikes as well. Mainly because they're fairly light.

Is it a road "comfort" bike or a carbon fiber racer type of bike? Skinny tires or something in the middle?
Bionx might not work well with skinny tires.

Or you could contact Yamaha and try to get the bike in my sig, which I call my "unicorn".

It's an older (1992 or so) Trek 1100. Aluminum framed road bike... 25mm wide tires.

Thanks for the speedy reply!

I put a bionx on a cyclocross frame. I used various tires on it: 700x28c, 700x32c, and 700x25c. Believe it or not, they all worked really well, including the 25c. I rode each at least 500 miles. I stuck with the 32c because it was more resistant to flats. The wheel doesn't have a quick release so it's more of a pain to change flats.

I have a 12 mile commute, and it makes a BIG difference between the days I take the regular bike out vs the bionx bike.

Since you have a road bike, you'll likely need 130mm drop outs. Bionx does provide that option though it's not really advertised. Also, they may be able to provide a presta valve wheel and a 9 speed freewheel which will be great for road bikes. And if you use 6V or 12V lights for night riding, I know they provide an option that allows you to plug right into the Bionx battery to power the lights.

What?

I never heard about this. That would rock since I use a BLT 12V 10W Hallogen headlight. I like the brightness, especially on dark trails, the the water bottle size SLA battery wears out in about an hour. Now if it were powered by the Bionx battery? Hmmm.....

Yeah, it's great. Too bad I didn't know about it before I got the system. It's not something you can add on later.

My "from scratch" ebike is based on a Nashbar cyclocross frame and a Wilderness Energy BL36 kit, 700c with 32mm tires. See http://www.captmonkeyrocket.com for a photo. A road bike or hybrid makes more sense for commuting, in my opinion.

Short answer: people tend to use heavier-duty bikes because the higher speeds of motor use cause lighter bikes to break.
In fact, motor use can cause even heavy-duty bikes to break.
But at least with MTB's, you can get some fat tires on it to act as shock absorbers.
