I recently purchased a new Magnum Mi5 from a local dealer in San Diego. I needed a commuter bike to get me the 3.5-ish miles to work. My main concern was hills, as my route goes from basically sea level to 350 feet above within that short distance. For the sake brevity, and since I've only had the bike 1 week, I'll skip a fully detailed review and skip directly to the takeaway's. The company As I mentioned, I purchased from a local dealer (https://sdebike.com) and they were great. The owner is enthusiastic and provides a great experience. Shortly after purchase I lost the key to remove the battery and they worked with me to contact Magnum to see what options I had. Communication was fast between Magnum, SD E-Bike and myself and they did everything they could. Unfortunately since the keys are unique to each bike there was little they could do. I ended up getting a locksmith to create keys for me (huge thanks to O'Brien Lock & Key) for $40. The bike The video review posted by Court sums up the details quite accurately and thoroughly. The only 2 cents I have to add are that, operating in pedal assist mode, the bike performs quite admirably on hills which is exactly what I needed. Attached are 2 screen grabs from 2 different routes I've tried. I can easily maintain 11MPH on the steepest portions of the ride, and I'm only using power level 4-5. The large dips in speed are stop lights. As far as battery, I haven't done a drain test. I got the battery down to roughly 30% and got in about 22 miles All-in-all, I'm quite satisfied with the purchase at$1699. The customer service was great, and despite the key issues up front (which were entirely my fault) its been as smooth as can be and provides me exactly what I need.
