My electric bike stopped working and wouldn't even power on. After trouble shooting with the vendor that the battery wasn't the issue, the vendor support sent several parts to install. At that time I contacted Darrell at Kaz Bike Repair. After installing the new parts, the bike still wasn't even powering on. Darrell was extremely patient and competent in communicating with the vendor support, and doing a multitude of tests and troubleshooting on his own to finally determine what the problem was and restore the bike to working condition. Darrell was very professional in keeping me updated throughout an extremely frustrating situation, and persisted in ultimately fixing the bike, when I think most people would have thrown up their hands and given up. His charge for all his work was extremely reasonable. I'm very grateful to Darrell and recommend him highly. read more
