FAQs

Which eBike conversion kit is best?

There isn’t one “best” eBike conversion kit for everyone — the right choice depends on your riding style, terrain, and goals. Some kits focus on easy installation and everyday commuting, while others prioritise power and off‑road performance. Think about whether you want a kit that’s simple to fit on a city bike, or a higher‑torque option for hills or long distances. A reliable conversion kit from a trusted brand like iHoverboard offers a good balance of compatibility, durability, and support for most riders.

Is an electric bike conversion kit worth it?

Yes — for many riders, an electric bike conversion kit is worth it because it lets you upgrade your current bike into an e‑bike at a significantly lower cost than buying a brand‑new electric bike. Conversion kits can:

• Add pedal assistance for easier riding up hills and longer distances.
  
  

• Reduce physical effort while commuting or carrying cargo.
  
  

• Extend the life and usefulness of a bike you already own.
  
  

If you enjoy cycling, want to commute more comfortably, or want a greener way to travel, a conversion kit adds real value without the expense of a new e‑bike.

Is a 750W electric bike legal in the UK?

No — in the UK, electric bikes used on public roads must meet strict legal standards: they must have motors no more powerful than 250 W and provide assistance only while you pedal up to 15.5 mph (25 km/h). Anything above 250 W or faster than 15.5 mph is generally classified as a motor vehicle, not an electric bike, and requires registration, insurance, and a driving licence. Higher‑powered e‑bike conversions (such as 750 W) are therefore not legal for road use in the UK unless they’re restricted to the legal limits or used on private land.

How fast would a 72V 4000W eBike go?

A 72 V 4000 W conversion (an extreme‑performance kit) can reach very high speeds — often around 55 mph (88 km/h) or more under optimal conditions like flat terrain and light rider weight. These powerful systems are designed for off‑road use or private land rather than public roads due to legal speed and power limits for e‑bikes. Actual top speed varies depending on the battery, controller, terrain, rider weight, and aerodynamics, but speeds above 50 mph are commonly reported for high‑wattage 72 V setups.
