Well, you have to take as you find. I have purchased a power plus from them and two folders. one of the folders had a small dent in the front mudguard ( it was all wrapped in the box so they couldn`t have known) I complained and they sent me a new bike and exchanged it at the same time with the old one within two days. The batteries are starting to show there age now and I`ve made up a 24V SLA one that works a treat.
The folders are OK for local runs or around town but my wifes power plus is still her bike of choice and we do have a number to choose from.
