Rear Wheel 72V 8000W Hub Motor Kit for Stealth Bomber Bike

Product Overview

The Rear Wheel 72V 8000W Hub Motor Kit is an extreme-performance direct-drive power package engineered specifically for Stealth Bomber steel e-bike frames and custom electric dirt bike builds. Built around a high-torque brushless gearless hub motor, this system delivers top speeds of 60–65+ mph (96-105+ km/h) and up to 185 N.m of peak torque. Compatible with heavy-duty 150mm or 175mm rear swingarm dropouts, the kit features ultra-thick 10G spokes laced into a DOT-rated motorcycle rim (or 100mm fat bicycle rim), a 72V 200A continuous sine-wave controller, dual Hall sensors, and a full-color UKC1 TFT Display. It is the ultimate high-power conversion solution for aggressive off-road riding and pit bike conversions.

Frequently Asked Questions (FAQ)

Q: Will this 8000W rear hub motor fit a standard bicycle frame?

A: No. This 8000W motor requires a 150mm or 175mm rear dropout width found on Stealth Bomber steel frames or heavy electric motorcycle swingarms. Standard bicycle frames (typically 135mm rear dropouts) are not wide or strong enough for this axle size and torque output.

Q: What battery specs are required to run an 8000W Stealth Bomber kit?

A: An 8000W kit requires a high-discharge 72V Lithium-ion battery with a Battery Management System (BMS) capable of handling a minimum of 120A to 200A continuous discharge current. We recommend you our 72V stealth bomber battery.

Q: Why is a motorcycle rim recommended over a bicycle rim for an 8000W motor?

A: At speeds above 60 mph (100 km/h) and peak torque of 180 N.m, standard bicycle rims can buckle or lose truing under impact. 19-inch and 21-inch motorcycle rims with 10G spokes offer far superior lateral strength, sidewall stability, and puncture resistance.

Q: Is an 8000W Stealth Bomber e-bike street legal?

A: No. Motors producing 8000W and speeds above 65 mph exceed standard e-bike Class 1, 2, and 3 power limits (which cap power at 750W / 20–28 mph). This kit is strictly intended for off-road riding, private property, or closed-course tracks.

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.

Q: Will I need to pay import taxes?

A: Import taxes are normally not charged for shipments to the US, UK, EU, and Australia. Additional charges may apply in New Zealand, Switzerland, Norway, Mexico, Argentina, Brazil, and other destinations.

Import duties and taxes depend on the destination, shipment terms, and local customs rules. Please confirm the applicable charges before ordering.

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

Put your bicycle on its kickstand or against a wall so that it’s stable.
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.
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.
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.

With no tire on your bike wheel, position the wheel vertically and hold it steady.
Take a measuring tape and press it against the inside of the rim, where the tire bead would normally sit.
Measure the internal distance from one side of the rim to the other (as shown in the image above).
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.
