The other reason for reviewers being biased negatively was the very poor experience with the earlier Schwinn e-bike model. This was chaotically programmed, the motor overgeared and it suffered many controller failures. They've obviously learnt, but I would still criticise the choice of a battery type designed for e-cars. E-bikes need high capacity with minimum weight and bulk, and SCiB doesn't fulfil that criteria.Don't be fooled by some of the reviews you can find on the web, all of them written in the context of it being a hi end priced bike. Which I think probably contributed to the model not doing well. Now you can pick them up for £500.00 or so (I got mine for £600) you have yourself a fantastic machine!
