Just bought a WATTBIKE Proton. Firstly it’s an excellent bit of kit, very easy to assemble, set up and connect to Watt hub. Currently training for a sportive and the Proton really suits my needs. Whole family now set up on it and they love it.

Wattbike Proton, 4'6" to 6'6"

I was able to organise a demonstration easily at Wattbike HQ. This process and experience was very valuable for us to make our decision. Our boxed wattbike arrived very quickly.
