What to Know Before Converting Your Bike to Electric in the UK

What to Know Before Converting Your Bike to Electric in the UK

Converting a regular bicycle into an electric bike can be one of the smartest upgrades you’ll ever make - but before you go ahead, there are some important things to understand.

At E-MY-BIKE, we specialise in professional mid-drive electric conversions that are UK road legal, high-performance, and fully warrantied.

Here’s what you should know before starting your e-bike journey.

1. UK Law: Know the Limits

In the UK, electric bikes (also called "electrically assisted pedal cycles" or EAPCs) are only road legal if:

• The motor is no more than 250W

• The assistance cuts off at 15.5mph (25km/h)

• The motor only assists while you’re pedalling

Anything above these limits becomes a motor vehicle and requires registration, tax, insurance, and even a driving licence. Unfortunately, many cheap DIY kits online exceed these limits - putting the rider at risk of fines or prosecution.

Our service ensures 100% legal compliance, so you can ride confidently without worrying about the law.

2. Not All Kits Are Equal

E-bike conversion kits vary wildly in terms of quality, performance, and reliability. Hub motors (fitted to the wheel) are common in DIY kits, but they:

• Struggle with hills

• Often use cheaper electronics

• Can unbalance the ride

Mid-drive motors (mounted at the crank) are more efficient, torque-rich, and provide a smoother ride - especially on gradients. They also work better with your bike’s gears.

At E-MY-BIKE, we only use high-torque mid-drive kits powered by genuine Samsung battery cells, all fitted by experienced technicians.

3. Safety & Wiring Matter

DIY kits often come with complex wiring, poor waterproofing, or vague instructions - increasing the risk of:

• Electrical faults

• Poor brake cut-off wiring

• Unreliable performance

Our conversions are fitted cleanly and securely, using waterproof connectors, integrated displays, and properly mounted battery systems. Every bike is tested before it leaves the workshop.

4. Warranty, Support & Peace of Mind

When you convert your bike with us, you’re not just getting parts - you’re getting a complete service:

• UK-wide collection & return

• 2-year warranty on fitting

• Support from a real technician - not just an email form

And if anything goes wrong? We’re here to help.

5. Conversion vs Buying New

Why convert instead of buying a new electric bike?

• Cost-effective - our service starts from just £995

• Custom fit - keep the bike you love, electrified

• High-performance - better torque and ride feel than many entry-level e-bikes
