Buying guide
Fast electric bike – 45 km/h and above
Compare electric bikes with a stated technical top speed of at least 45 km/h. The range includes different frames, motors and batteries. Start with the specifications of the exact version and look beyond its maximum speed.
In short
- Stated technical top speed of 45 km/h or more.
- Distinguish maximum speed from a limited riding mode.
- Compare batteries and range using the same riding mode.
- Choose frame size, brakes and tyres for your intended use.
How to choose a fast electric bike
What does a 45 km/h electric bike mean?
This collection starts at a stated maximum speed of 45 km/h. A limited riding mode may have a lower speed. Check which mode and version the figure refers to; a model sold in another market under the same name may have different specifications. Stated top speed is not a promise of identical performance for every rider, load or surface.
Motor and brakes
Distinguish nominal motor power from peak power. Compare torque, motor position and how assistance is controlled. A high wattage alone does not describe the riding experience. Check the brake type fitted to your chosen variant and the availability of wear parts; hydraulic brakes and dual motors are not requirements for this collection.
Battery and range at higher speeds
Compare battery capacity in watt-hours and check which battery version is included. Establish whether the range figure is for pedal assistance or riding without pedalling. Maximum stated range should not be read as range at top speed. Load, hills, temperature and riding mode affect each charge. Also explore our long-range electric bikes.
Frame, weight and storage
Check recommended rider height, saddle adjustment and permitted load for the exact model. A folding design is not necessarily easy to carry. Compare the bike's weight and folded dimensions with your storage space. Wide tyres and suspension should suit the surface you use; they do not prove a particular speed or range.
Check your chosen version
Match speed, battery, frame and equipment to the selected variant before buying. A speed figure or a 25 km/h setting alone does not establish road approval: check the vehicle's classification, documentation and local rules. For other formats, browse all electric bikes.
Frequently asked questions
Which models are included in Fast electric bike?
Electric bikes with a stated technical maximum speed of at least 45 km/h, including exactly 45 km/h. Price, frame style and motor power are not additional selection criteria.
Why might a model have a limited 25 km/h mode?
Maximum speed and speed in a limited riding mode are different specifications. Check the version being sold and the mode to which its stated top speed applies.
Is maximum range measured at top speed?
Do not assume so. Check riding mode, battery and test conditions. Pedal-assist range cannot be compared directly with range without pedalling.
Does a fast electric bike need two motors?
No. Selection is based on stated maximum speed. Compare each model's motor, nominal power, peak power and torque separately.
What should I check to find the right size?
Compare recommended rider height, frame entry, saddle adjustment and maximum load. Also check weight and storage dimensions, especially if you need to lift or transport the bike.
