Good product overall. Took a long time to be delivered but it was worth the wait (I went with the preorder GO kit). I enjoyed the installation process which is simple enough, the hardest part being the pedal sensor. I can see how they have made certain compromises to make the kit universal, for example with the cable lengths - results in a bit of a mess, compared with bespoke e-bikes with internal cable routing. But for the money I am impressed with the ease of installation and the performance from the motor. Transforms an old utility bike into something you want to ride.
