    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Got an answer from Leaf: "A and B are the same. But, because works with 60V battery. It's too fast. Sometimes, we will use slower speed winding rotor."

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Can anyone tell me if there is a physical difference between the two motors I have listed below? The link to each motor is after the Item ID #. A. Rear Rotor Winding - 48V 52V 1500W hub motor part, Item ID #LBM481500RN-WRP...

    The GMAC CAN do regen...it does not have a freewheel clutch like the MAC: https://ebikes.ca/product-info/grin-kits/gmac.html A 10T GMAC laced in a 26" rim would work or a 5T Leaf 1,500w motor would work...those two would be my recommendation. Use the Grin Tech Motor Simulator to compare the...

    Questions..... What motor were you running before you installed the QS205? Is the performance increase a result of multiple changes? Just wondering how the two motors compared...if that is even possible considering there may have been changes besides the motor. Thank You...nice looking bike...

    MXUS 3000 Hub Motor - V1 V2 V3

    Crystalyte offers the H55 motor in a 140mm width. This is a link to the Crystalyte web site: 无标题 1 The H55 has a stator that is 55mm wide. The H55100 is going to be the next motor I buy.

    Peeps, I need help with finalizing a choice for a motor, QS205, anything better?

    What about the Crystalyte H55 series of motors...the stator is 55mm wide. They have multiple widths over locknuts...including one that is 135mm. The H55 motor is relatively lightweight so if you push huge amperage, it may over heat quicker than a motor with more mass. At one point and still...

    Same battery in the trike and the bike? That is my last guess :).

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    What diameter wheel was being driven when you had it in the trike and what diameter wheel is it in now? I am wondering if the load on the motor has something to do with the stuttering because my MAC would not do it when I had my 3 speed switch set to 60A but at 40A it would stutter a little bit...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Don't know if there is any correlation but my Leaf 1500w motor will act like it trips a circuit breaker if I try to start off with anything more than the tiniest amount of throttle. If I pedal and get the bike moving very slowly, the problem disappears much like you said when you pedal "about 2...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Thanks...I drilled a .108" (drill bit OD) hole in the side cover on the freewheel side just outside of the largest gear. Almost identical in position to what you are showing. The syringe that you put the Statorade in with has a really small tip on it and it easily fits in the .108" hole...I'll...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    How do you guys add Statorade to your motor? I want to seal all of the interfaces using Permatex Ultra Gray RTV and in the future, I'd prefer NOT to have to take a side cover off to add Statorade. Talked with Grin Tech and they recommended sealing my motor because the carrier fluid used in...

    I wonder if EM3ev.com would be an option...they currently don't offer a specific "Stealth" battery but it might be worth contacting them since the market for a Stealth Battery is going to be increasing for quite some time IMO.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Does Leaf dish/offset the rims they lace? I haven't checked mine yet. Thanks for the dimensions.

    Thanks, I'll compare the drawings available on the Leaf web site and see what I can use.

    I have the ERD for the rim, just need the dimensions of the motor...in particular the diameter of the spoke circle hole pattern.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I need to order spokes to lace my 24" SE RACING J32S rim to my 1500w Leaf motor...does anybody have ANY of the dimensions I will need to use a spoke length calculator? I have asked Leaf in the past and I got no help. My calipers will only go up to 6 inches. Thank You

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    It can cause some problems because the axle gets twisted in both directions with Regen. The twisting can work things lose and/or wear them if you don't keep everything tight.

    The white wire may be used for a temperature sensor...when one is installed. That is just my guess.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    When lacing a 1500w Leaf motor to a symmetric rim, is there any offset/dish required to get the tire centered in the frame? Been doing some runs with the Grin Tech Motor Simulator and it looks like I'll need to switch to a 24" rim/tire if I want to keep my temps below 120C. I ran my MAC at...

    Building a Powerful Ebike

    Just a recommendation for anyone that wants to build an ebike and ride over 30 mph... A Direct Drive (DD) motor with a stator that is 35mm wide or wider and approximately 205mm in diameter is the smallest DD motor I'd consider due to potentially over heating. With Statorade, a 35mm stator can...

    "shorter and growing shorter", I can relate...I have lost about 1.5" in the past 10 years. Do you have a donor bike yet? I was looking at the Walmart web site for bikes that came with 24" wheels and the biggest issue is whether my 14s6p triangle shaped battery will fit in the frame. The 24"...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I asked Leaf if there was any physical difference between the 48/52v 1500w motor and the 60v 2000w motor and their answer is below. "A. is the 2000w motor and B. is the 1500w motor. A:can work 48v or 52V or 60V B:recommend work with 48v or 52v battery.Had better not work with 60v battery...
