Paid extra to receive power pack earlier. 5 months later - it still doesn't work. easy to set up but one part wrong shape so had to be replaced before it could be assembled. They sent the same part again! Next delivery was the same part again and a near fit part but it needed filing down to fit. Then power pack would not fit the handlebar shape so new bracket need to be ordered. This one no longer sat on the handlebars so each time you want to change the power level you have to stop. It worked in the end well - for two/three journeys. Then it started to fail, only giving a short power boost as the pedal was pushed down and then stopped powering. Then it stopped powering altogether. Zoom call followed and technician decided on the 'solve it all' new bracket for the battery. This arrived and did not make any difference after being fitted. Next, it was decided a new controller would do the trick. Arrived, fitted - made no difference. Now another Zoom call in several days time. I have pleaded for someone to come and sort it but they will not. I have offered to drive through London to take the bike to Swytch - they will not agree. I have asked twice for a refund for the extra payment for early delivery and the charges I have incurred and they have said they will sort it - they have not. It is a standing joke in my neighbourhood and at my office. The sales video says"we are there to help if you need" As polite as the people are they are not helping the customer and the end result is frustration, anger, reputational damage for the all singing smiling image that is portrayed. Very sad - especially as the intention was to support an innovative new business. Meanwhile the customer is totally inconvenienced and out of pocket.
