I've recently purchased the Go+ version of the Swytch system and it's been a great help. Living in a rather hilly area, I was finding that the uphill gradients were killing both my knees and lungs. Considering I am an overweight 56 year old who hasn't ridden a bike properly for over forty years, I wasn't too surprised to see I needed some assistance. I had been following the Swytch guys for a while, so when I purchased my hybrid bike, I always kept them in mind if I needed to convert. The conversion was a simple enough process, but I soon realised before fitting, I wouldn't need the hydraulic brake sensors as the motor isn't so intrusive that I had any reservations about it causing any issues whilst out. There was a slight mix-ip in communications to receive my refund, but it was sorted eventually. After multiple rides, the GO+ battery seems to sit nicely in the predicted range too, will have to see how it does in the cooler months though, but very happy with it at the moment. I'm still waiting for the locking frame adapter to arrive, but all-in-all it's a great product that fits my needs perfectly.
