18 inch electric motorcycle hub motor kit

1. The rear wheel diameter is 18 inch motorcycle motor kit and the rim width is 2.75inch (70mm). Thank you, it would be great if I could get the same rim with the hub motor. In case, this causes problems, I think a 2.5inch rim width should also work.

2. The hub motor that makes 50mph (i.e. the one that you describe in the 1.8-16inch 2000w hub motor) sounds great for me. Do you have a more detailed sheet on it, i.e. the torque, rpm etc?! I would like to go with this one then.

3. Great, thank you. Do you have more details on the dimensions of the shaft (diameter and shape) such that I could already start checking how I can mount it in my swing arm.

4. Sounds great, so this will be my option of choice.

5. Okay, I will need the brake to be on the left side, so this is my option of choice, thanks.

6. How much more would be the 60V battery and can you estimate the enhancement in power of the 18 inch electric motorcycle motor kit? I think 52V will be fine for me, but just to know.

7. Thank you, so there will be no additional custom fees when shipping it to Finland?

Finally, how can we proceed with the ordering once all remaining open questions are solved as I cannot use the products from the web shop directly due to the special needs?
How long will be the lead time roughly?

I will go with the 1.85-18 rim then and I guess with the 60V battery.
I will mention all as you explained, thank you.
Before ordering, I will have to figure out some minor detail so i guess I will place the order some time next week.
Looking forward to have the engine.

18 inch electric motorcycle conversion kit

I am interested in the electric motorcycle conversion kit you offer. I am electrifying an old Kawasaki KE 125 (1976) and would require the fitting electric hub engine for the rear wheel and all other components (controller, battery, brake). Before I can order, I have a few questions:

I would need a 18inch rim (at least 2.5inch wide as shown in one photon in this kit https://www.leafbike.com/products/electric-motorcycle-kit/1.6-18-inch-48v-52v-1500w-rear-electric-motorcycle-motor-kit-1275.html?VariantsId=10576 , but it could also be wider as there was a 2.75 inch rim installed before). However, as for the hub motor, I would like to have a 2000W motor with max speed 50mph as described here for a 16inch rim https://www.leafbike.com/products/electric-motorcycle-kit/1.85-16-inch-48v-52v-2000w-rear-electric-motorcycle-motor-kit-1272.html?VariantsId=10413. Is that possible?

Do you have a faster hub motor in a motorcycle kit too?

The drop out would need to be 215 mm. I measured 200mm between the swing arms (inside to Inside distance) and 215mm at the outside (outside to outside distance). Is that possible? Or is there another way to adjust it?

I assume that when buying the kit, this means that I only have to install it but the rest fits together already?

How much more would be to get the color display LB08HU instead of the standard LCD-S830?

In addition, I would need the disk brake to be mounted on the left side with your motor flange (https://www.leafbike.com/products/electric-bike-parts/motorcycle-disk-brake-pads-rotor-flange-1252.html) such that I assume that the cable location should be on the left?!

I would also order the disk brake set for motorcycles that you offer (https://www.leafbike.com/products/electric-bike-parts/180mm-motorcycle-disc-brake-1056.html) and a battery.
For the battery, I am wondering how much of a difference the 52V (https://www.leafbike.com/products/lithium-battery/52v-20ah-lithium-battery-1224.html ) compared to the 48V makes in terms of performance of the hub engine?

How much would cost in total incl. shipping?
The shipping would be to Finland. How does it work with the customs? Do you have any information and experience with shipping it to the EU?

Look for an Electric motorcycle motor kit

I just bought a gas moped (49cc) and plan to convert it to electric with your electric motorcycle kit. It looks like I’ll need at least 1500W rear hub motor, although I’m willing to go higher if needed (2000W?). Someone on a forum indicated that you do custom windings and I should reach out to you, but I’m not an engineer and can only describe how I’ll use the moped – I can’t offer what specs are best, or if this is within what you can offer.

I would prefer a solid wheel (no spokes) but on your site those only go to 1000W?

The original moped rear wheel is 17″ with a M62 3-17 tire. I haven’t removed the tire to get the exact fork distance, but I think it is around 175mm

I don’t need a high top speed, 20 mph maximum and mostly I will be in the 0-10 mph range. However, it will be constantly going up and down hills, including several hundred feet of about 15 degree incline. So, I need good low-speed torque.

I weigh about 200 lbs, and the moped (and the tools I’ll be carrying) adds another 100-150 lbs.

This will never be used on public roadways, only on my farm. I live in the USA.

I haven’t started looking at controllers or batteries yet.  My first step is to identify the best hub motor option, then I can worry about the rest. 

I’d prefer a 17 inch casted electric motorcycle hub motor if I can get one with enough power / torque at low speed.
