ACX 250W Road Legal Bundle

Why this one is different
Everything else on this site is built for private land. This one is built to the UK EAPC rules, so it is treated as a bicycle in law.

Assistance cuts out at 15.5mph (25km/h)
Pedal assist, the motor helps while you pedal
Rider must be 14 or over. That is the only rule
Legal on roads, cycle lanes and cycle paths across England, Scotland and Wales
What is in the bundle
250W rear hub motor pre-laced into a wheel
36V lithium battery and charger
Controller and LCD display
Pedal assist sensor
Brake levers with motor cut-off
Wiring loom, connectors and torque arm
Fitting guide
Check this before you order
Rear dropout width: 135mm. Measure the gap between the inside faces of the two rear frame arms where the wheel sits.
Axle: quick release or bolt on, both fine.
Freewheel: screw on, up to 7 speed.
Not sure? Email us a photo of your rear dropout and we will tell you before you buy.
Delivery, read this properly
This one is not held in UK stock. It ships direct from our supplier, so it takes longer than our other kits. You will get a tracking number as soon as it leaves. If you need something in three days, buy one of our UK stock bundles instead.
Warranty
12 months against manufacturing faults on the kit. 24 months on the battery pack.
Add to your build
The torque arms stop the motor axle tearing out your dropouts, which is the one failure that writes off a frame.
Add the battery bag
Protects the pack and straps it to the frame. Not included with any kit or bundle, and the one thing every customer asks for after their kit arrives.
Battery ships within 1–3 working days for UK customers. Standard shipping for the kit is 50–60 days (shipped by sea). Need it sooner? Express shipping is available at checkout for an additional cost, arriving in 15–20 days.
30-day return window on unused kits. 12-month warranty on motor, controller and battery. Reach out via the chat widget for support.
Do I need special tools to install the kit?
Most kits can be installed with basic bike maintenance tools. Each kit comes with clear, step-by-step instructions.
Is the kit water-resistant?
Yes. Key components are protected against splashes and light moisture. Avoid fully submerging parts or using high-pressure washers.
Are conversion kits legal?
Regulations vary by country and region. Many areas permit motors up to 250W; 250W stickers and speed limiters can be used to comply with local laws.
How far can I ride on a single charge?
Range depends on battery capacity, terrain, rider weight, and riding mode. Actual distance may vary significantly.
