I ordered my Swytch kit to convert my Carrera 3 hybrid bike and was very impressed with the results. The kit was easy to fit and took me about an hour (not a cycle maintenance guy) to fit in total and then I was off. The motor is a 250w and i got the eco pack battery which is plenty to help me along the way on long rides. The motor is responsive and pulls well at all assist levels. From 1 level of assist on the eco pack I can get 35km of distance with a mix of hills and flats. There will be a lot of comments around delivery times from my own personal experience I ordered mine in April and received it at the end of July so over their estimates but considering what was going on in these times it wasn't and issue for me. I was kept well informed with their weekly/bi weekly updates and have had quick responses from any queries i sent to the customer service teams. Overall a great quality product and if you can deal with the wait times due to the business model then a great purchase.
