Motors
In the U.K. the maximum road-legal motor size is 250 Watts*. These motors are commonly powered by 36 volt lithium-ion batteries and are available in different sizes.
​
There are three types of motor in use nowadays: rear hub motor powering the back wheel, front hub motor powering the front wheel and the mid-drive motor which is located at the bottom of your bike frame where your pedals are.
​
This last one - the mid-drive motor - is in our opinion the one that gives you the best experience and is also the most efficient.
*What about that asterisk?
Well, to clarify, electric bikes for use on the road and advertised as such must be 250W. However, there is no limit to the size of motor that can be added to a bike for use 'off-road' - on tracks, private land and anywhere which is not a public highway. Such motors are popular with mountain bikers who happen to own some woodland or a field or two or know someone who does
Batteries
On an electric bike, your battery is your fuel tank. This is an easy enough concept to grasp on a car. The bigger the tank, the further you can travel given a certain engine/motor size. But, as with a car, how far you can travel on an e-bike on a full tank, or battery as is the case, also depends on the size of the motor and how you ride.
There are a lot of misperceptions surrounding e-bikes and numbers when advertised. If you see a 625 motor or a 500 motor, this doesn't mean the motor is bigger or smaller. Those numbers refer to the output power of a fully charged battery and have nothing to do with how powerful the motors are. They simply state how much fuel is in a full tank.
These numbers should have the suffix Wh (Watt hours) so, a 250W motor and a 500Wh battery should allow you to travel for 2 hours at full power. However, that may not get you very far; around 30 miles assuming you cycle at a steady 15 miles per hour along a completely flat surface on a warm, windless day.
That's rather unlikely in the real world.
​
In the real world, how far you can go on one battery depends on so many things: how hard you pedal, the weather, the level of assist you use, the terrain, be it hilly or flat...
​
With so many variables, it's almost impossible to work out so, if you see an advertised claim, sprinkle with a pinch of salt.

Our Batteries
​
For all 250W motors we include a 36v 14.5 Ah (522Wh) battery.
​
For 750W and 1000W motors we include a 48v 19.2 Ah (922Wh) battery
​
Each battery comes with a mount which is connected to your motor (we do this for you) and is usually attached to the part of the frame which goes from your handlebars to your pedals. This keeps weight as low as possible.

​
Batteries are detachable and each comes with a 3 Amp mains charger so you can charge your battery anywhere there is a socket.
​
And a set of keys to lock your battery to your bike.
​
Displays
It's always nice to know what is going on so each motor installation comes with a display controller. This is your e-bike dashboard.
​
From it you can set up to 9 levels of Pedal Assist (PAS), monitor your speed, your battery voltage, your trip and more. You can even switch on your front light.
Small full colour display unit with integrated PAS selector buttons. Left side mount.
Larger, centrally mounted display unit with separate PAS selector/control buttons. Comes with built in USB port for phone, GPS or battery pack charging.
