Impressive tech and surprising delivery! Firstly the delivery, it was surprising because it arrived out of no where EARLY and I wasn't in to receive it , better tracking would have been nice and I could have avoided a few days of hassle but it was a few weeks earlier than expected so overall I was happy. Then the kit itself, I struggle a bit with bike maintenance like flat tyres, but I actually managed it OK, I got my partner to help with the tyre bit as it hurts the fingers getting the tyre off but apart from that I managed the rest myself. And the boost and the feeling when you start riding is just wow so I would absolutely recommend this!
