At least not any way I can think of. Hi, You cant really do a lot about this, small gears simply cant take the high power mid drives deliver on the limited amount of teeth that make contact with the chain. Good luck though! Yes, the programming software, actually the internal controller firmware limits the maximum to 30A. Which settings should I assign to the 9 assistance levels so that they become 5, to always have the maximum engine torque, but with reduced speed? Yes, everything works fine but the settings are far from perfect while set to default. Would this scenario cause damage?

If you want 5 stages, you should still fill in the 9 assist levels, I believe it picks assist levels 1,3,5,7,9 as the corresponding stages if you choose 5 stages. Which often is more accurate than the display does. So it will probably have trouble connecting to it as well. Thank you for your useful information. Thats a weird problem, thats not known to me. I do know that permanent magnet brushless motors like the Bafang motor most of the time will operate more efficiently at higher RPM. As mentioned in previous posts decreasing current will also decrease torque. Stop increasing when you feel that the power becomes to much for your bike to handle. bbshd instructions rewrite.txt Avec cette configuration, encore quelques soucis : -coup parfois, et difficults de relance de niveau 2 3 voir 4.

So overall your plan to set the current limits low, just cycle along as a strong cyclists, to maximize range, is a perfectly fine strategy! Het batterij voltage of percentage is het enige wat is af te lezen. Many thanks for your reply! Number are all over the place from different website. I have not viewed the following link; presumably it is a video version of these instructions: https://youtu.be/6fvJVz30LU8 The ebike will then just get up to the maximum speed that can be reached with that amount of power.

Thanks. 28 wheels A lot of owners had issues with this and thought the settings would fix that throttle issue.! I am concerned about reliability, not performance, so if it comes out-of-the box at 18A I will probably leave the programming alone (initially at least) or can I achieve a stock current limit of 18A by keeping below a certain assistance level (using the stock programming). no u need to remove a link or more it will strip the cassette and start to brake teeth ive bin through 3 now lol ive had my bbshd and my 52 v batt for over 2.000 miles and i flashed it when i got it im just looking to c if there was any new programs or flashes there are 7 versions.
