Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

How difficult is it to change out the phase wires? Are there any guides or diagrams in this thread showing some of the process? I know there's pics located somewhere in this thread showing the motor case open, but I don't have the time to look through all of the pages to find it.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

One of the nice things about brushless motors is that they are very tolerant of a wide range of voltages. As far as how many amps to use, it all depends on how often you'll be using high amps. I feel the ideal temp is around 140F, but it is widely regarded to keep the motor safe by not exceeding 93...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

My Leafbike motor is now ordered. I requested 1000W version built into a 26" double-walled rim with 5T wind, 10K NTC thermistor, and cassette compatibility. Cost was $304.88 including shipping. I went with a cassette version instead of freewheel because replacement 11-34T freewheels are not made any...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

If you are getting the motor from leafbike, get ready to change the thermistor to a 10K. I like your setup, currently my front chainrings 30/39/50 but is to low for what I want at my cadence. Did you buy your ring set or build it? I was going to ask them to install it for me. One of the members her...

Re: Car replacement E-bike that fits me

Can be powered by either an electric motor alone OR with combined human power. CANNOT go faster than 28 MPH without applying human power. No more than 750 watts. This change in the law was recent. There used to be a speed limit of 20 mph without applying human power, but no power limit, the weight ...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Just to be clear, the 1000W version can reliably handle a 21s pack of Li Ion, correct? The salesperson at Leafbike recommended the 1500W version of this motor if I want to run it at more than 48V. I'm planning to get a 5T wind of the 1000W motor with cassette compatibility and a 10K NTC thermistor f...

Re: Car replacement E-bike that fits me

So put the toe in back and added couple mm of toe in to it. but if I ride around 40km on a worn road it feels wild and I don't like that. The width from the edge of tire to edge of tire should be narrower in the front of the wheel than the back of the wheel by 1/16th of an inch. It sounds to me lik...

Re: ICE Sprint 26 with BBSHD build. (recumbent trike)

Right now the trike has a 36t chainring and a 11-32 cassette. I see that Sunrace sells a cheap 11-40 cassette that fits and i have the old chainset with a 38t and a 52t ring on it. I can for fairly cheap convert to 38-52 chainring and 11-40 cassette. I can also convert to 42t chainring and a 11-46 ...

Orin was able to reach more than 40 mph in it on flat ground at Battle Mountain, NV. There is no motor of a...

Re: ICE Sprint 26 with BBSHD build. (recumbent trike)

This is a nice trike. I'd recommend keeping the front derailleur. Try doing 25 mph over a rough section of road where your trike gets hammered by potholes and see if the chain stays on. If it comes off, for sure you'll want the front derailleur as a chain stay, or at least SOME type of chain stay in...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Thank you all for the info. The seller wants to meet a few weeks from now. I'll have plenty of questions that they may not know the answer to, but since it is possible to take the motor apart to install new components for my requirements, then I know I can make it work regardless of what it has in it.

Re: Ok, so I crashed again today...Is it time for a trike in the city?

I believe the idea that they may be more visible to motorists, especially here where drivers have to be more alert for obstacles in the road than they do in the States, but I don't trust any of them. You shouldn't. Ever. They can be looking right at you and claim they didn't see you. Unless I've ma...

Re: Ok, so I crashed again today...Is it time for a trike in the city?

For this reason, I’d say go for a trike. You’d be much less likely to ride the sidewalk on a trike. Then, a clever build for a commuter trike is a tadpole fast enough to merge with trafic, with a high flag to be seen. I find riding a trike to be a lot less stressful than riding a bike on the whole....

Yep trikes are the way! otherDoc Before I first rode one, I wasn't expecting I'd like it as much as I did.

Whatever you choose to ride, if you don't have it already, get suspension. If you continue to stick with two wheels, get full suspension, and get wide fat bike style rims/tires, something suited for going over bumpy terrain at high speed, to facilitate quickly and easily switching between street and...

At 4K the tempter sensor needs changing or need to put one in if not using the kit to match the one you will be using. That is if you want to motor to last.
Any recommended models of this temperature sensor?

Re: Ok, so I crashed again today...Is it time for a trike in the city?

I think you might go very wrong if you try to operate such a thing in regular traffic in Southern California. The law limits you to 28 mph motor assisted. Even if we fudge up to 30 mph, that's not enough to let you flow with traffic. And in So Cal, traffic can get very congested and I'd imagine dri...
