Frequently Asked Questions (FAQ)

Q: Will this 5000W MTX rear wheel kit fit a standard 135mm bicycle rear fork?

A: No. High-power 5000W motors feature wider stator cores requiring a 150mm rear dropout width (spacing). Ensure your frame or rear swingarm accepts a 150mm hub spacing before installation.

Q: What is the difference between the 72V 40Ah and 72V 40.6Ah Stealth Bomber battery choices?

A: The standard 72V 40Ah battery features a 100A BMS with a 4A charger. The 72V 40.6Ah Stealth Bomber battery features a heavier-duty 120A BMS, a 5A fast charger, and a physical casing shaped specifically to drop into standard Stealth Bomber steel frame enclosures.

Q: How far can I ride on a single charge with the 72V 40Ah battery?

A: Range depends heavily on riding speed and terrain. Expect approximately 35–50 miles (55–80 km) at moderate speeds (25–30 mph), or around 25–35 miles during continuous full-throttle off-road riding.

Q: How do I know if the kit fits my bike?

A: Check your existing wheel size and rear dropout width against the available configurations. Also verify tire clearance, brake compatibility, and battery mounting space. Use our wheel size and dropout measurement guide before purchasing.

Q: Can I buy the 5000W electric bike kit without a battery?

A: Yes. You can purchase the 72V 5000W hub motor conversion kit without a battery.

Q: Is this 5000W e-bike conversion kit legal for street use?

A: A 5000W system capable of 50 mph (80 km/h) exceeds Class 1, Class 2, and Class 3 street-legal e-bike limits in most regions. This complete conversion kit is intended primarily for off-road trails, private property, or closed-course racing. Please verify local e-bike power regulations.

Q:  How long does shipping take?

A: Estimated delivery is 10–15 business days by air, 28–30 business days by sea to the US, or 30–35 business days by railway to the UK and EU. Actual delivery times may vary.

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.
