Will it fit?

Will it fit?

There are two main considerations before buying a kit. Will the motor fit into your forks or rear dropouts? And will the battery fit on your bicycle frame? If the answer is yes to both of these then you are good to go with converting. Read this blog for more information to help you decide which kit options are most suitable for your bicycle.

Fork Width

bike forks

If you are installing a front motor, check the width of your forks.

There should be a gap of 100mm between the bottom of the forks. Most bikes are like this, but some (particularly folding bikes) have smaller gaps which make them unsuitable.

You should also check the space between the forks all teh way up and compare to the motor diagram (available in the product info) to check whether the motor casing will fit OK in between the forks.

Sometimes, if the forks are too narrow, there can be friction between the motor casing and the forks. In this case, buy some TORQ spacers to just gently spread the forks outwards slightly and this usually solves it.

Wheel Size

Bicycle wheel sizes are weird! Sorry, it’s not our fault but they are.

The most important thing to note, is the name of the bicycle wheel size (e.g. 26 inch) refers to the outer diameter of the tyre. Depending on the tyre, the actual bicycle wheel can be different sizes, for the same nominal wheel size. For instance, there are some 26″ wheels that use thin tyres, and they have larger wheels inside the tyre than 26″ wheels that use fat tyres….

The final thing to check, is where will your battery go? Don’t buy a battery before checking where you will actually mount it.

Generally speaking, if you have a large mens or unisex triangular frame, you can fit any type of battery, but the downtube battery is preferable.

Ladies frame cannot accommodate the downtube battery, so for them you should use the frog type or rear rack type which puts the battery at the rear.

For folding bikes, the frog-type is generally the only option that works.
