Foldable e-bike that interests me - A question on controls

Postby ColinOldnCranky » Sun Sep 04, 2011 6:54 pm

I checked out a foldable ebike on the train today.

The ebike I saw interested me because it had such a low step-thru that it would suit my partner. And I have seen the model before without electircs but I never took a close look.

I noted the weight of the battery and hub so something like this would benot so good for the back of the car but ok for leaving from and arriving home. HOwever I also have a VERY steep drive which she would not be able to accomodate.

So, question. How good are controls these days for powering it up and down while dismounted to the side for someone who has to negotiate the up and the down with caution and very low speed.

The one I checked out looked damned close to this:

Not sure about these little bikes with 20" wheels from my own experience.

The throttle control on my bike was really good for pushing it up the bike ramp in the middle of the staircase on Sydney harbour bridge. I imagine this ramp is comparable to a steep driveway.

She'd have to press down with some extra weight on the front wheel to ensure that it wouldn't flip over...

The thing I would look out for would be a strong "return" spring on the throttle to make sure that if the rider (or in this case pusher) has to release the bike for some reason the throttle will close quickly and safely.

I'd tend to (just slightly) favour a motorcycle type rotary throttle over a thumb lever type simply because it looks like it might be a bit more difficult have the rotary catch on something (a low hanging branch or piece of clothing perhaps) and stick open. A very minor problem though I would have thought.

If you haven't already been there, there's a small shop in Victoria Park which deals in small personal transport systems, including e-bikes. They might be able to help you with any questions. They're in the same road as the BMW shop, heading away from the city.

I recently bought a similar folding bike for riding to work - 23 kg including the battery (about 3 kg?), it goes nicely into the boot of my hatchback (though I mostly get the husband to lift it in). You take the battery out before folding it to make it easier to handle. I previously had a cheapie Internet job with a brick-like lead acid battery - don't bother with something like that!

Mine has a rotary throttle which would definitely get it up a very steep hill when pushing, as well as variable pedal assist. It also has a button to turn off the throttle if you don't want to get a sudden surprise as you push.

Maybe see if a bike shop will let you take one on trial for a couple of days to see if it suits?
