TLDR 22" wheel generic BLDC Hub Front wheel spacing 6kv I think. Will check with a different controller to be sure if someone cares. no disk flange Radial Lace to generic power circle rim 22" tire included In St. Louis Missouri. Will ship in the US $100 Shipped sound fair? This is a mystery brand fr...

Been getting a lot of questions about this lately. Its tentatively sold to e-biker who is just waiting on me to get the shipping finalized. I'll try to go back in the order I was contacted if for some reason this sale doesn't work out.

Thanks

What about trying them in parallel?

We should start a section on the forum where people post small item shipping requests. There has to be somebody flying from the US to AUS in the next few weeks. A sprocket in a carry on bag wouldn't be a big deal.

#35 chain does not have rollers only bushings. I don't know why it is the standout in that regard but I don't want to spend money to find out. With the type of high reduction ratios we all end up with on these bikes 219 is a nice option. I believe that bore on the 22 tooth sprocket I got from Buller...

Throttle signal from the controller is 5v. The throttle measures 5k ohms closed and a few hundred ohms wide open.

Probably the same guts but its a front motor for sure.

It is a charming piece of history. It is not wide enough for a rear 135mm mount. It is made for front mount. It also has no freewheel or disk flange so I don't know how you would use it in a rear unless it had no pedals. Might make a better mid drive with as sprocket screwed to the outside shell. I ...

Speaking of machining, how long have you been at it? Do you program setup and run parts for a living or just some of those tasks? I'm curious because I personally do all three at work. I even have a 5axis machine center to play with but I feel like everyone builds cooler stuff than me. I am relative...

Alright guys. Good news. I put 3mm of spacers per side on a non suspension fork and it looks like it will fit and spin just fine. It also clears the IS brake flange and the torque arm lines right up so it would be super easy to make torque arm that uses the brake mount. Actually the torque arm will ...

I cant find shipping for less than about $60.

3. That's true and is what I think I'll need to do. To retain a big rear sprocket to keep chain forces down I'll need to run a big front sprocket - eg to get a 15:1 overall reduction with the clutch primary reduction in the train, with a 90t rear I'd need a 21 tooth front. Looks like I might be mak...

My lmx 30mm is 45kv. It came with a 12 tooth 219 sprocket. I run a 92 or 94 tooth rear on a 24" wheel on 20s so 75v nominal. This gearing does 48-50kph and has enough torque to wheelie on a long wheelbase bike when set to 4kw max. If a human rider on a trials bicycle can side hop over a meter with h...

Clutch or not I think you will be pleasantly surprised by the abundance of smooth controllable torque an electric motor has to offer. Just fyi, the lmx seems to get along nicely with the nucular. Here is some amazing work with the lmx and nucular! https://endless-sphere.com/forums/viewtopic.php?f=6&...

Seems like quite a divergence from the original plan but still looks like it would be fun to ride. I agree with Altair about eliminating the clutch for the first try. When you were trying to convert a full weight moto trials bike it made sense. You are so far away from that with a mountain bike that...

I honestly don't know. I have some throw away forks I don't mind possibly bending I'll try to spread them with some washers and see if I can get some pictures. Probably wont be until the weekend though. Sorry.

I'd be ok with 40 but I'd guess it will be another 40 to ship. Sadly wheels are just big from any angle. Would you be ok with that?

I'll try to get a more specific shipping quote.

Thanks

That rust :shock: Yeah, I know. Its crazy. I was pleasantly surprised when it ran. The motor was donated to a bike based charity in my area. They don't really mess with ebikes for liability and tech support reasons so I try to sell any ebike stuff for them. It's not pretty but if anyone wants to ta...

2old Got your PM and figured I'd respond here since you just made me realize there might be some fitment issues with this motor on standard mtb forks. It looks like the proper spacing for a front mountainbike fork but it rubs on my suspension forks. The stamped steel torque arm integrated into the m...

Thanks for the link.

This motor looks like a lot higher build quality than the stuff we all mess with now days. I was considering drilling and tapping the side cover for a sprocket mount and using it for a cargo trike. Definitely not a hot rod motor but it looks way overbuilt in the quality dept.

$75+Shipping OBO Parts are in St. Louis Missouri Helping my friend sell some ebike parts he was given. This is a Heinzmann 500watt brushed DC motor kit. It came from one of those recumbent trikes with the really long front end. The motor says 36v so thats what I tested it on. It runs about 150rpm at...

$100+Shipping OBO Parts are in St. Louis Missouri Helping a friend sell some ebike parts he was given. I don't know the history of these items. Motor will need some work as the wires look to have been damaged in a spin out event. Kit says Voilamart if that helps anyone figure out exactly what the sp...

Interesting. Should help a bit with the hook moves. Have you checked to see if 2wd is allowed with the club you compete in?

True but just to clarify, it cant de-rate or control anything without being hooked to the throttle. It can be used as a gauge only but offers lots of nice features when the throttle is connected.

If you dont want the CA to control the throttle or brakes that is fine. The CA is still a nice dashboard and battery monitor. The shunt is connected to the S+ and S- wired on the CA-DP connector in your diagram. Most controllers have an internal shunt somewhere but it might be easier to use an exter...
