Frequently Asked Questions (FAQ)

Q: Will a 72V 5000W rear hub motor fit my standard bike frame?

A: This motor requires a 150mm(MTX or motorcycle wheel) or 170mm (for wheel)rear dropout width with sturdy dropouts. Due to the high torque (100 N.m), using heavy-duty torque arms on both sides of the axle is strongly recommended to protect your frame dropouts.

Q: Can i use this electric bike conversion kit to build a stealth bomber bike

A: Yes, of course. you can choose the 19" & 21" motorcycle wheel or 26" x 4.0" fat wheel or 26" x 2.6 wheel if you want to build a stealth bomber ebike.

Q: What battery specifications are required to run a 5000W e-bike kit?

A: A 5000W kit requires a high-discharge 72V Lithium-ion battery equipped with a Battery Management System (BMS) rated for a minimum of 80A to 100A continuous discharge current. We would like to recommend you the 72V 26.1AH, 72V 35AH triangle battery or 72V 40AH block shape battery. If you want to build a stealth bomber bike, you need a customized size battery to work with, please check the steatlh bomber battery, you can choose 72V 26.1AH-72V40.6AH battery. 

Q: How fast does a 72V 5000W e-bike kit go?

A: Under standard riding conditions with a fully charged 72V battery pack, a 5000W rear hub kit reaches top speeds between 50 mph and 55+ mph (80–88+ km/h).

Q: Why is an MTX double-wall rim important for a 5000W motor?

A: At 5000W, standard single-wall or light bicycle rims can deform under rapid torque transfer and trail impact. MTX double-wall aluminum rims offer wider rim profiles and reinforced walls to maintain wheel integrity.

Q: Which wheel option should I choose: MTX Bicycle, Motorcycle, or Fat Tire?

A: Choose based on your frame setup and riding style:

  • MTX Rim (20"–29"): Best for converting standard bicycle frames with 150mm+ dropouts where keeping total bike weight lower is preferred. Please be aware the MTX rim width is 38.9mm.

  • Motorcycle Rim (19" or 21"): Best for extreme off-road riding, heavy dirt bike swingarms, and riders seeking maximum rim strength and tire puncture resistance at 50–60+ mph.

  • Fat Tire Rim (20"x4.0" / 26"x4.0"): Required for fat tire e-bike frames (typically 175mm or 190mm rear dropouts) to ride on sand, snow, and loose trail surfaces.

Q: Do the dropout spacing requirements change for the fat tire wheel option?

A: Yes. Standard MTX bicycle rims typically fit 150mm rear dropouts, whereas 4.0" Fat Tire wheels require wider rear dropout spacing (usually 175mm or 190mm rear dropouts). Be sure to check your frame's rear fork width before choosing your wheel option.

Q: Where does the kit ship from, and how long does delivery take?

A: The product information lists shipping from China by air, sea, or rail, depending on the selected delivery method.

Estimated delivery times provided for this product are:

  • Air shipping: Approximately 10–15 business days.

  • Sea shipping to the US: Approximately 28–30 business days.

  • Rail shipping to the UK and EU: Approximately 30–35 business days.

These are estimates and may vary depending on destination, customs processing, carrier schedules, and seasonal demand.

For details, see our Shipping & Delivery Policy.

How to measure wheel size and dropout of a bike

How to Measure a Bike Tire (How to Measure a Bicycle Tire)

In the bicycle field, the wheel size is the size of the bike wheel after you install the tire. So when you get the tire size, you get the bike wheel size.
If you have a bike tire on your wheel, you can generally find required measurement information on the tire wall (side of tire – see picture below).
Tire walls usually display the size as the picture below. 
If you can’t find the sizing on the wall of your tire, here we show you the methods to get your bike wheel size. 

The Standard Method (Easiest and Fastest Ways to Find Bike Tire Size) 

The standard method is to measures the tire width and tire diameter in inches.

How to Measure Bike Wheel Size with the Standard Method

  1. Put your bicycle on its kickstand or against a wall so that it’s stable.
  2. Place the bottom of the tape at the lowest point of the tire (on the ground) and measure in a straight line to the centre of the bike wheel to find your wheel radius (as shown in the image above). Multiply your wheel's radius by two, then it is the wheel's diameter. it is the wheel size.
  3. Measure the tire's width by placing the type across the top of it like the picture below. the number you got is the tire width. Be sure to list the diameter first, followed by the tire width.
  4. Bike wheel diameters are rounded to the nearest half-inch, so if your measurements are just over or under, round up or down to the nearest size.

How To Measure a Bike Wheel (Rim) for Tire Size

If you do not have your bike’s tire to hand, you can determine the tire size by measuring your bike’s rim width in millimetres as well.
Based on the average tire and wheel combinations currently on the market, the following charts illustrate the coinciding tire size and rim length.
Many rims will display their size somewhere, but some rims may be missing this measurement. 
If you cant find measurement on your wheel’s rim, follow the easy steps below that will help you determine the appropriate tire sizes your rim can handle.
  1. With no tire on your bike wheel, position the wheel vertically and hold it steady. 
  2. Take a measuring tape and press it against the inside of the rim, where the tire bead would normally sit.
  3. Measure the internal distance from one side of the rim to the other (as shown in the image above).
  4. Take this width and apply it to the correct table below.

Road Bike Rim Width to Tire Size Chart

Mountain Bike Rim Width to Tire Size Chart
Measure of Wheel
20" -- outer tire: 495mm dia.; rim: 410mm dia.;
24" -- outer tire: 600mm dia.; rim: 517mm dia.
26" -- outer tire: 650mm dia.; rim: 573mm dia.;
700C -- outer tire: 690mm dia.; rim: 635mm dia.
28" -- outer tire: 710mm dia.; rim: 650mm dia.

How to measure the dropout of your bike

The dropout of your bike is important, it can decides if the electric bike kit can fit your bike or not. So before your purchase of an ebike kit, please measure the dropout of your bike first.

Bike dropout is literally called frame spacing, is the inside distance between the two fork ends (drop outs) where the wheel fits in. it is very easy to be measure just by removing the wheel and holding a ruler to measure the place where the wheel came out. please check the following picture.
