Aus - High powered Chopper 10kw+ Mini-hubmonster

Hello, I am selling off some ebike parts. I have a long chopper/cruiser frame with a mini-hubmonster and a 120v Kelly controller running the bike. Currently the batteries are toast and I dont have the interest to rebuilt it up so I am selling it off. Just add a 120V nominal battery and you will have...

Aus - Powerful Low chopper bicycle 8kw+

Hello, I have my purple monster low chopper bike for sale. I bought it back of the owner I built it for and replaced the battery pack along with wiring up a Kelly controller to make it a much easier bike to handle at 8kw. It had previously been running comfortably at 14kw so it can easily handle alo...

Re: Offset hub alloy wheels

Best thing I can suggest is find a car wreckers and get yourself some of the aluminium space saver wheels from a Mercedes or some European hot hatch car. 16-18" are available in about 3" wide or less. Most single side swing arm setups for motorbikes are even bigger then that at 5". I am also looking...

Re: GM motor/controller, constant "stalling" and stuttering

Well hopefully you do get it sorted with just wiring issue as been the problem. It kinda does sound like that if you are having issues even when coasting down a hill etc. Yeah with the controllers it would be nice if they would hold a history of faults so you could actually track what was causing it...

Re: Sabvoton Overclocking

Should be as simple as open up the controller fine the 2 phase wires that go thru the hall sensors to read the current big square things, prob blue. Cut the wires before the sensors, grab 2x 8awg wires and solder them to the original single 8awg wire, feed one thru the sensor and then use the other ...

Re: Are the ADAPTTO kit $$$ as people think....?

well documented in regards to the adaptto is only for fairly standard hub motors. Go for anything high speed like a mid drive etc or something abit different and its alot harder to setup and get right. Adaptto is going to have a bit of competition with recent controllers coming out with bluetooth di...

Re: Ultra lightweight CV Joint Axles and low RPM Motors

more as a link for a supplier for usable parts in the project he is doing. 500rpm is probably more the at the wheel speed so there could easily be many stages of reduction or even a single large stage using 219 chain as a example would be very easy. Probably one of the easiest in this power range is...

Re: Golden motor 48v HPM3000B problem

Sounds normal to me :) yes try changing the yellow and green hall wire connections first. If that fails try the other 4 hall combinations. 1 should work perfect but may go in the wrong direction tho.

Re: Golden motor 48v HPM3000B problem

to be honest i have had a few of these motors and the actual wiring between phases and halls does not match on most of them. So please do go through and check the different hall connections, pretty sure i had to swap green and yellow on about 2 motors out of 4. Also in regards to turning the shaft, ...

Re: Solar-Electric Beetle project on crowdfunding

Sine wave controllers are a pretty good idea only if you can get one with great regen settings. Adaptto is one but its also very under used as you would want to be charging the car while driving if its sunny out. I would use John from CRs hub motor 93% efficient, the mid sized one, 2x adaptto minis ...

Vertical colums for the wheels? Makes life pretty simple, get 4 mid monsters from John, mount them above the wheels, gear them down to your wheel size and speed requirements and done. Make it a nice simple chain connection thats easily repairable and cheap, use a pair of cheap controllers that john ...

Something that looks like a bicycle :) Do you want suspension?

Re: Adaptto Mini-E/Max-E Owner's Thread

For everyone's info, if your experiencing speed limiting on high speed motors you will find that pwr timing has a large effect on the top speed too. Just make sure you calculate your actual e-rpm so you dont get too close to the max.

Willow, I am guessing the controller still lights up and everything. From the main screen go to the side until you get to the screen with the hall diagnostics on it. Slowly spin the wheel and hopefully its a simple issue with one of the halls been dead should get all the 1 to cycle through :) I have...

A bit of a wierd one but what about a FTC trike with the lean controlled for the most part by the steering? Have the lower suspension arms with a flex join on the under side of the frame. With the upper arm do similar with a flex point at the top of the frame. For suspension using the "ski" method, ...

Re: Outrunner motor to tire friction drive increaser?

Simplest that comes to mind is sand paper glued on to the shell, works really well but if you dont set it up right you will end up with very worn out tires. How is your friction drive setup? Does it pull itself into the tire the more power you apply, ie on a slide mount or a pivot mount?
