Re: ENDUROEBIKE.COM

Fitted a 72v to 12v converter, Is yours a 60v bike or 72v (76v if 24s lifepo4.) Because my bike needed a 86v to 12v dc converter (Charge voltage?) Only complaints, so far is the stand keeps moving, no matter how much you tighten it, I put some extra screws in it to stop it moving consider putting a...

Re: ENDUROEBIKE.COM

I agree, be cautious more than anxious. Imo, you could likely make a much nicer build diy, for less money. As a firsttimer, maybe don't plan to save much money, but get alot of experience which will help to use/maintenance/upkeep. I did my first diy this year, and just grabbed a purpose built frame...

Re: Has anyone tried one of these Chinese enduro bikes?

I don't know how I missed this particular thread, as it's EXACTLY the project I was also building (In my Bedroom lol) during, these months this post was active. OK so I also bought just the EEB frame set (direct tho not thru em3ev) Dealing with the company was actually very easy, just as it's China ...

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

I typically run at an average of 1500w with frequent peaks exceeding 2000w, in a 26" wheel with the 5T, and I have NEVER seen temps exceeding ambient, even on 7-10 mile rides on 70 degree days There must be a problem with the temp sensor because you should see at least a few degree more as ambient....

Yes I saw Justin 5ml test data ferrofluid on another thread, but just like venting it too requires drilling (if only 1 small one, and might be messy,) plus careful silicon sealing of the cover, I think I may just opt for the 4T Mxus v3 with aluminium stator for better cooling but after reading Neptr...

I don't have an external shunt, and use my built in controller shunts, of which there are 3 in series according to the builder, Lyen 18fet 4110 dropping the 4ohm to a 1.333 intern resistance. But even knowing this abt my controller and my custom batt details, each cell apparently has a ≤1.5mΩ (AC im...

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

Actually, the motor power (or actually load) is sort of the key here. If you ignore the motor simulation entirely and just look at the black Load Line you see the power necessary to propel the bike at various speeds ('load' on the sim tables). 'Motor Power' equals 'Load' (the power to propel) at th...

I know if I give in to re-opening the batt pack, I'll end up ripping the 60a-120a bms out I wouldn't do that. Then you're going to need to manually balance the pack whenever you charge it up, and you won't have anything to protect the cells from too deep a discharge, since as you get down to the bo...

Re: Using leafmotor/leafbike 1500w as mid-drive motor?

other thing is spinning up this thing. With 0.35mm laminations, 40k-erpm should be possible without excessive eddy currents. At 23 pole pairs this means 1700rpm :shock: Meaning one could gear this at 3:1 for a motor speed of 1500rpm at a wheel speed of 500rpm (around 60kph or 38mph in a 26" wheel) ...
