We love our switch bikes...only wish it could go farther than 50kms on a charge. Doesn't always work, cutting in and out. Switch sent a new battery adapter, but still having issues with it. Not wanting to spend additional monies as we are looking to purchase e-bikes in the future. Price is economical for a beginner bike. Haven't had to return anything to weigh in on the refunds, etc. Downside would be that they do not ship to Canada for free and had to use an agent in the US. It would be really good to have a dealer here in Canada that would take us to the next level in bike / battery maintenance and or the purchase of the next gen battery now being advertised.
