I run a 6t MAC on 36v on my recumbent trike, it tops out at 25 mph.

A guy at work has a petrol bike, it goes nicely but he is constantly repairing things on it. In comparison, my MAC motor has been going for two years and has only let me down once (melted connector).

My clutch locks up for a couple of days every couple of months. I've got a spare sitting in the shed ready to go on, but it always sorts itself before the weekend. It does suck a little to ride when it's locked (like riding into a stiff headwind), but it still gets me to work and back OK.

Have you thought about something like this for the gear display? http://www.adafruit.com/products/1347

This may be a little odd, I just took the test and wound up with a borderline score, I'm sure 10-15 years ago I would have far more extreme. Perhaps I've mellowed with age. I'd never paid any attention to autism or aspergers until I read The Speed of Dark by Elizabeth Moon and realised how much...

Mine started to stick a while ago and then magically unstuck again (the day my spare arrived). In the few weeks since, it has stuck and unstuck again once more.

As we all love modifying cheap Chinese stuff here, I think this would be a good place to share this: As these are close enough to a Magicshine 808 the diffusers should fit, various vendors sell a diffuser (search for macishine wide angle) which makes the hot spot around three times the width...

Couple of observations (note, I've never done this myself). I don't think I'd trust spring loaded terminals in a ebike situation, batteries get bounced around a lot and I'd be concerned about them not making great contact. Also, how do you plan to hammer 1" tubing to be less than 18mm wide? Or...

I'd have to peel the S off the sticker on the side...

I pulled my wheel off to fix a bent RD mount, put it back on and the clutch works again :shock: Just got confirmation that the new clutch should arrive on Monday so I guess I'll have a spare...

Good to hear, I'm a little irritated that I managed to break it on 10s 40A, but that's life I suppose... I somehow managed to bend my RD hanger while I was stuffing around with it last night so I didn't ride today. I'll sort it out over the weekend and give it a go next week.

Thanks for the offer, but if anyone is going to experiment on the motor it will be me :D I'm now thinking I'll let it go for the moment, fit the new one when it arrives then weld this one up as a 100% reliable spare for the future...

Then I pedal :) It would suck, but I can get there... Do you just weld the bearing to the housing? I might pull it apart this weekend and have a play.

The one-way bearing in my MAC motor appears to have seized solid so the motor doesn't disengage any more. I've just flicked an order to cell_man for a new one, but the question is can I ride it until the spares arrive? Apart from the gear noise, it still seems to ride OK and the drag doesn't...

Good to hear about the gears. I was thinking about this motor the other day; with the torque sensor hooked up after the gears, wouldn't you get a different reading depending on what gear you are in? Is this something you notice when you are riding?
