I have just fitted my swytch kit having received it last week. All I can say is it an excellent system and very easy to fit. The only mistake I initially made was with fitting the disk brake. The screws for the disk brake are in the hub already but you need to remove the plastic spacer that is being held on with the screws to ensure the disk lines up. If is wasn't for my mistake it would have only taken me 30 mins to fit it. I am managing to get around 50Km per charge but that is on the maximum power setting. As the battery only takes about 3 hours to charge its not an issue to worry about. I did take the optional throttle but have not fitted it yet and I don't think it is really needed as the cadence detector on the pedals allows the power to kick in quickly. Overall it will allow my miserable commutes in the rain to be more enjoyable and to overtake those horrible electric scooters that have been overtaking me in the past.
