20" - 29" Wheel 1500W / 2000W Cassette Motor E-Bike Kit with SW900 / UKC1 Display

Product Overview

The 1500W–2000W Cassette Rear Wheel E-Bike Conversion Kit turns standard 20" to 29" (and 700C) bicycles into high-speed, high-performance electric bikes while preserving your bike's modern multi-speed drivetrain. Built specifically for 8-speed, 9-speed, and 10-speed push-on cassettes, this direct-drive brushless hub motor delivers speeds between 28 mph and 40+ mph (45–65 km/h). Featuring multi-voltage capability (48V, 52V, and 60V systems), a heavy-duty sine-wave controller, and your choice of an SW900 LCD or full-color UKC1 TFT display, this kit is engineered for smooth shifting and hill-climbing power on 135mm rear dropout

Frequently Asked Questions (FAQ)

Q: What is the difference between a cassette motor kit and a freewheel motor kit?

A: A cassette motor features a modern freehub spline that slides directly into standard 8, 9, or 10-speed cassettes used on modern mountain and road bikes. A freewheel motor uses older threaded-on gear clusters (typically 7-speed). Choose a cassette motor if your bicycle currently uses an 8-speed, 9-speed, or 10-speed shifter set.

Q: How fast can this cassette motor go?

A: Actual speed and range depend on battery voltage and capacity, controller settings, wheel size, rider weight, terrain, weather, local regulations, and riding style.

The following are approximate reference speeds supplied for a 26-inch wheel and a rider weighing approximately 70–75kg on city streets:

Motor Power	Approximate Reference Speed
1000W	45 km/h
1500W	55 km/h
2000W	60–65 km/h

These figures are estimates, not guaranteed performance. Actual results may differ, and applicable electric-bike regulations may restrict permitted motor power or speed.

Q: How Far Can the Kit Travel on One Charge?

A: The riding range depends primarily on the battery's usable energy, along with rider weight, terrain, speed, tire pressure, weather, and riding style.

This 1500w/2000w cassette motor ebike kit does not include a battery, so the final range will depend on the battery you choose. A larger-capacity battery generally stores more energy, but no specific range can be guaranteed without testing the complete bike setup under defined conditions.

Q: What size battery is required to run the 1500W and 2000W cassette motors?

1500W Motor: Requires a 48V, 52V, or 60V Lithium-ion battery rated for at least a 35A continuous discharge.
2000W Motor: Requires a 48V, 52V, or 60V Lithium-ion battery rated for a minimum 45A continuous discharge.

For compatible battery options, see:

Important: Match the battery's nominal voltage to the controller specification. Check continuous discharge current, connector compatibility, and controller requirements before purchase. A battery's peak BMS rating is not necessarily its continuous rating.

Q: Will this 1500W / 2000W cassette motor kit fit my bicycle?

A: Yes, provided your bicycle frame features a standard 135mm rear dropout width (rear axle spacing) and uses 20", 24", 26", 27.5", 28", or 29" (700C) wheels.

For measurement guidance, see the Bicycle Wheel Size and Dropout Measurement Guide.

Q: Is a cassette included with this hub motor kit?

A: The base motor hub includes the freehub splice body designed to accept your existing 8, 9, or 10-speed cassette, allowing you to retain your original rear gearing setup.

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.
