I have had an evolve board for 12 months, it was the first generation and I have had loads of fun. The newer models have a bigger motor and are better at climbing and stopping by all accounts. I haven't had any reliability issues and have been able to ride it every time I wanted to. Recently though the range has reduced and I am hoping its just a single battery cell that needs replacing or rebalancing. I haven't opened it up to look and will most likely send it to evolve to diagnose. It still gets more range than the boosted board so its very usable.
I think battery problems will be discussed more frequently as electric boards age. They make up a significant portion of the board cost and I hope suppliers have a good strategy to help customers when problems arise.
Boosted boards look awesome and I can't wait to try one someday. I only ride for fun and its typically 45-60 minutes at an average speed around 14-16mph, so a boosted board falls a little short in their range. I was wondering if Boosted had considered having an 'eco' mode that only runs one of the motors enabling extended range?
