Ordering and delivery took a very long time On a big hill the battery drain is immediate and sometimes drops to 2 bars but does 'recover' over time Extra £50 for a black wheel - never paid a premium for a black wheel before Range claimed to be 20miles but this is very questionable Discrepancy between battery life on handlebar display and LED's on battery System is heavy, despite claims to the contrary - Have been spending more time on my normal (non-electrified) bike Whilst it achieves the desired result, expectations were high based on the PR from Swytch, but these expectations were a little deflated once used a few times - Swytch should have been more transparent during ordering Some items described in the instructions not possible with kit
