Wheel Size 
 
20”, 24”, 26”, 28” (700c) Bikes come with varying wheel sizes – 20” is the best size for folding bikes. In general the larger the size the smoother the ride but this has to be thought about in conjunction with how tall the bike is – and can you get onto it. 
 
 
 
Battery 
 
Lithium – offers the most efficient battery available at present. They give a lightweight, long range, long life option that has transformed current bikes. They are not the cheapest though 
Lead Acid –SLA (sealed lead acid) battery - cheap to replace but heavy and limited range 
Frame 
 
Folding – these frames allow the bike to be folded down to compact the overall size. Useful for transporting in cars, buses or trains or storage at home 
Aluminium – lightweight and often moulded into stylish shaped frames 
 
 
 
Range 
 
Up to 30 miles- Battery ranges are given as a guide but can e subject to may considerations. They can be affected by temperature, rider fitness, terrain, wind, tyre pressure and several other factors 
 
 
 
 
 
Power 
 
PAS- Pedal Assist System – pedal driven power 
Throttle- Working from either thumb or twist grip. Will get you going without pedalling. 
 
 
 
 
 
 
 
 
The type of pedal assist system used to make the bike go. 
Torque – Works by measuring the pressure you put on the pedal and multiplying that input 
Magnetic – simply by turning the pedals this type starts to work 
 
 
 
 
 
Derailleur – traditional variable ratio gear sprockets as found on most bikes 
Hub – new version sealed gears in the wheel hub. Clean operation with next to no servicing needed 
 
 
 
 
 
Lights 
 
Integrated lights are connected into the motor’s battery system. Independent lighting is run from regular AA or AAA batteries. Most use high visibility LED lights 
 
 
 
 
 
Brakes 
 
V Brakes - also called Rim brakes as they have brake blocks either side of the wheel rim. 
Disc Brakes – Pads sit either side of a disc and offer effective all-weather braking 
Hub Brakes – are enclosed in a drum. Although heavier also offer good all-weather protection 
Motor 
 
Front Hub, Rear Hub - Hub motors are mounted in the front or rear wheel and drive or pull the bike accordingly. 
Crank motors sit in the centre of the bike and drive through the chain. Efficient and needs less power from the battery generally
