Electric Bikes - Got a new bike yesterday

So I got myself a Giant Sedona DX last night. Great comfort bike.

I found the mountain bike was putting too much stress on my wrists and my posture was bad for my back. So I went for a comfort bike instead.

I didn't move over the Bionx stuff yet. And boy do I regret not doing so!

Today I rode the Sedona in pedal only form to the office. Slow as heck and I got there all sweaty. It's a very comfortable bike and I like it alot but without my Bionx on it, it's not a very good commuter. Well, at least not for a guy like me who works in an office.

So the first thing I do when I get home tonight is to move over the Bionx system to the new bike. Fortunately, the Sedona has 26" wheels so it's a simple swap. The frame seems to be a bit bigger so the battery install might be easier this time. My only concern is the brake install. Should I just move the brake lever from the old bike or should I attempt to remove the brake switch and magnet and install it on the new bike?

I'll be following this video for the install: http://ca.youtube.com/watch?v=M5evWA1yIDk

PICs of the new bike coming soon.

Update
======

Bionx system transfered over to Sedona. A few things though:

1 - The notch on the torque sensor doesn't exactly point downwards. How do you adjust that?
2 - I need to change the gearset. I forgot my old bike had 9 gears in back and the Sedona only has 8. I'm planning on going from the Shimano megarange low gear all the way up to an 11T. The Sedona is a comfort bike and not quite as fast as the mountain bike. So 11T is fine for the top gear.
3 - I still need to move over the brake sensor and magnet. I rode it to work this morning without the brake sensor. So I simply didn't get the regen braking. No biggie. And I had to keep the assist at 2 or lower.

This is now a very comfortable cruiser.

Y, that notch is impossible to remove without the special notch remover. You'll need to ask any electric bike store that carries Bionx for it. You could also try contacting bionx directly (there's contact info in the book... not sure how updated it is).

I managed to move my brake sensor just by using a thick strong double sided 3M tape you can find at any hardware store.

Wasn't quite clear about what you're aiming for in the gear set. If the Sedona originally was geared for an 8 speed, I would buy the Shimano 7sp 11-28t freewheel. I believe 7sp are spaced slightly further apart than 8sp, but close enough to be compatible. It's probably easier than changing the shifters.

I hope you have many safe and enjoyable miles on your new ride.

There is a fairly detailed post on the Visforvoltage forum regarding the notch, I think I wrote it last summer. It describes the tool which is called a three jaw puller, this is available at most auto parts stores. The BionX tool would be better, but possibly more difficult to find.

That notch isn't perfectly vertical as it's supposed to be. It points a little forward and about 45 degrees off from vertical.

I wonder if it has the similar effect as a car's engine of advanced timing? It's not perfectly vertical but with the angle is it a bit "advanced" ? I say this because the assist still does work pretty well. I don't really see much of a problem.

The notch orientation is critical for correct strain guage reading. The further it's away from pointing downwards, the more the bumps in the road will be misread as the pedalling effort instead of the pedal effort. That's what Bionx told me a couple of years ago.

Based on that, my guess is that when the notch is pointed correctly downward, the strain guage is located in the rear of the axel. So if you pedal, it presses the wheel forward against the rear part of the axel. If the notch points to the front instead, the strain guage is now under the axel, so any bump you hit will be read as pedalling effort instead. If it's off my 45 degrees, then you probably will have to pedal a little harder to get the same amount of assist and it will also be mixed in with noise from bumps in the road.
