This setting determines how gentle the ramp-up is on your power on start. Starting up too fast can kill your motor’s controller so beware. I am using the lowest setting published in the article I linked above. Here again, why create a situation where you could end up blowing your controller or chewing up your chainrings? I stay on the conservative side. Stop Delay I am not sure how Karl shredded his gear so easily….. but my guess is he was using a controller that was not properly tuned for the motor which caused it to get excessively hot too fast. Our customer service goes way beyond the minimum requirements of helping with the kit itself. You will be able to get advice on everything from frame selection to gearing. There are many riders with the High Voltage BBSHD upgrade kits who are only too happy to share there experience and expertise. Some motors are sold configured with BB-Sensor-32. Others with DoubleSignal-24. BBSHD motors reportedly have 24 sensor signals per rotation, which points to the latter as the proper setting. I have tested both and found zero difference in performance or behavior.

Whats with the Assist 0 setting of 1 and 1 above? On newer BBSHD motors, if you set it to anything besides 1 and 1 you wind up disabling pedal assist. I’ve also heard it said if you want to use your throttle while you are at Assist 0, then you set Assist 0 to 1 and 1. Regardless of the actual effect, the motor doesn’t behave desirably at Assist 0 unless you use 1 and 1 there. Our extensive quality control means that our products are thoroughly tested and ultra-reliable by industry standards.The fact that you can still use your gears makes it even more versatile. You can use a low gear for climbing and a high gear for high top speeds. If you are planning on using multiple gears, I would highly recommend installing an additional gear sensor. This sensor will cut off power when the gear switching action takes place. This will prevent your derailleur, cassette, or chain from breaking when you accidentally would switch gears under high load. Ride and feel Unless you sandblast it. That might kill it. Feel free to test it and let me know your findings. My terrible battery shield. So nobody steals my battery 🙂 How It Rides

The gear sensor helps achieve smoother gear changes by pausing the motor during shifts. The kit includes brake levers for cable brakes, but with hydraulic brakes or integrated gear-brake units, you need to attach brake sensors. These sensors stop the motor when braking to prevent conflict with the brakes. Warranty Programmed for 2800W, of Assist levels (Power / Speed Map) are set within the display and will scale accordingly. This mid drive motor is made by Bafang, and often distributed as an “8fun” motor. They’re the same thing.The NT Battery case typically installs onto your drink bottle mounts along the top surface of your down tube. Its measurements are: 36cm long x 8.2cm wide x 12.5cm high. The table below states the maximum possible power output for the 48v and 52v batteries. Bafang Motor

Attempting to reprogram the controller may cause damage and invalidate any warranty to the controller The motor is built to take much more than the 30A that it is limited to. In fact, Luna Cycle sell controllers that can handle 60A and up to 72V like this one here! The BBSHD’s settings are presented on three separate screens: Basic, Pedal Assist and Throttle. The Pedal Assist Screen (2 of 3)You can lower the risk of controller failure by using a 48V battery instead of a 52V battery. The controllers tend to fail more often with 52V batteries. So in my opinion you should only go for the 52V battery if you absolutely want to get the most amount of power out of your BBSHD. Using a 48V battery will still give you a crazy amount of power, so the decrease in reliability does not way up to the increase in performance in my opinion. But it’s this weeks project at the Luna Lab and we love doing out-of-the-box stuff when we aren’t shuffling boxes. As mentioned before we needed to change to a 24 inch wheel to keep the suspension from hitting the controller on big dips. In this 24 inch wheel we decided to install a Rohloff which we know has no problem putting up with 3000 watts of power and also give us an amazing 526 percent of range so we will have the lowest of low grannies and the highest of high speed gears. Derailleur systems are preferred over IGH systems (IGH systems can often not handle the extreme power of the BBSHD, research this thoroughly before installing a BBSHD on an IGH drivetrain) The kit is supplied with a thumb throttle, so the bike can be used like an electric motorcycle if desired. These throttles are not particularly good for modulating the power and function more like an on/off switch. Reprogramming the controller can make the throttle more user-friendly. There are also aftermarket twist throttlesavailable.
