When I got my original BBS02 I used an Eggrider (I don't recommend them) to dial everything in where I thought it would work best for me. Then I experimented with those setting some using a data cable. When I installed the BBSHD I didn't change a thing just to see how the factory setting worked for me, and have left them alone since. Jackasses and businesses that want to sell to jackasses push the BaFangs to their limits (and beyond) shortening the life of the motor and increasing bike maintenance and part replacement significantly. I bought two more controllers, tested each to know they work and carry one with me whenever I have the front panniers mounted. BaFang sets them up to last longer and with far less outright failure. I very seldom ever use more than 500W and probably less than 1/2 of 150nm of torque, you don't need to if you can use the bikes gearing the way God intended. If I have 130 to 150 lbs. of gear on the bike and pulling a 90 lb. trailer having 1 1/3 h.p. on tap lets me know I can still ride anywhere that I want to ride. The old "it's better to have more than you need than less" philosophy. The funny thing is that it's easy to have a high-speed ebike if that's what you want. It's more about gearing than it is h.p., but jackasses want little motorcycles that are both quick, and fast even if that means minimal range and that isn't what the BBSXX series of mid-drives were designed for. If you want a Class-1 to 3 ebike (by the 2002 CPSA definition) they're almost perfect. I've told every person that asks about owning an ebike the same thing for almost 7 years now... find the perfect bike for how you want to ride, hang a BBSXX mid-drive on it, find the largest pack that the frame can hold (not two small packs... that's a selling gimmick for morons), and you can have a better ebike than any comparable manufactured ebike on the market. If you want fast, you can make it fast. If you want it to crawl through sand, snow, and mud, you can have that. If you want it to be able to climb or have the longest distance possible or pull a loaded deer cart 8 miles back to your truck, you can do all those things. I wanted an ebike that would ride further than I would ever want to ride in a day, that was comfortable enough to be able to push that limit for years, that's reliable, self-maintainable (up to a point, I'm not a "wrench"), and most important of all that can ride anywhere in America that bicycles are allowed, that means a Class-1 ebike. 37+K miles, with yearly maintenance and part replacement, but... I also have Rohloff Speedhub (I cannot possibly recommend them enough), arguably the world's best suspended touring bike frame, coupled with the best components. I saw one online vendor guaranteeing 1000 miles on their ebike, a whole thousand miles. 99% of ebike riders don't want a great ebike, they want a cheap ebike, using a BBSXX lets you have the best of both.
