What happens if the magnet comes off?

[mike killay]

On my Tonaro Enduro there is a magnet bolted to one of the spokes on the rear wheel, it passes what seems to be a sensor on the frame. How important is it, what does it do?

If it's part of the bike's electrical system, it's probably the road speed sensor to keep the bike to the legal limit.

Otherwise these are used with bike speedometers to record speed and mileage etc.

Hi

Is it part off a pedelec sensor

I took mine off the Bighit and it raises the assisted speed from about 15mph to 18mph. What range are you getting from your battery? i am seeing 50 miles regularly over moderate hills here is Hampshire, mind you not the Swansea Himalayas, i am from Tenby originally

I had a look at this bike and can't see the advertised models having any sort of display, though Mike may well have a newer model which does have one.

however because of their use for a speed display, the magnets are very common things to find on bicycles (even push bikes) so its not a complete disaster if it were to come adrift, replacements are only a few quid and widely available.

From what Shep says, it must be the speed sensor. I thought it was a wheel balance weight but found that it was magnetic.

I've only just got the bike, I did a 10 mile run and the lights remained the same. Problem here is that the first two miles were all down hill free wheeling, but coming back up those two miles was a revelation of just how good the bike was. I pedalled most of it because I was uncertain about the new battery. I tackled the last half mile which is about 1 in 7 initially in first gear and pedalling, but soon had to change up to third. It would have throttled the less steep parts but I wanted to be sure to have enough electricity for the steeper part. I arrived home as fresh as a daisy. Doing this years ago on an unpowered bike saw frequent rests, pushing the bike up the 1 in 7 and collapsing at home.

No it does not have a display, must be the speed sensor.

Many thanks to all of you,

Mike

A reviewer of the Bighit on the powerpedals website, also confirms the speed increase by removing the magnet.
Just out of interest, if the motor drives the main crank, does that mean that the pedals spin when power is applied?

No, the chainwheel is also freewheeled on these crank drive bikes. For example. trhe Panasonic unit bikes have three freewheels, at the back wheel as normal, at the motor's chain drive sprocket and at the chainwheel.
