Bafang 48V 750W BBS02 Ebike Kit

The Bafang 48V 750W BBS02 Ebike Kit with ebike battery pack option

EM3ev were the first company to have high quality IRFB3077 mosfets installed into their 750W BBS02 Kits. This was back in June 2015. This is when we finally managed to convince Bafang to fit some mosfets, that we supplied to them back in the spring of 2015. Bafang quickly realised this modification made a big improvement to the controller reliability. As a result they fitted the same IRFB3077 mosfets into all the 750W BBS02 kits they manufactured from then onwards.

We had no desire to make a big deal about this fact, at least not until we read the misinformation spread by certain suppliers, stating that you can only be sure that the upgrade mosfets are fitted, if you buy from them, or suggesting that kits bought from China (where all Bafang Kits are manufactured) may not be fitted with IRFB3077 mosfets.

Don’t let any delusional/dishonest suppliers, tell you that only their motors come fitted with upgraded mosfets. All 750W BBS02 kits manufactured after ~August 2015 were fitted with these upgraded mosfets and they have a been standard ever since, on ALL 48V 750W BBS02 kits.

Programming the Bafang 48V 750W BBS02 Ebike Kit

Regarding controller hot-rodding. We do not hot rod our Bafang kits (not exactly sure what the hell that is supposed to mean, when all these kits are restricted to no more than 25A). Nevertheless, we do set them to have full throttle in all PAS levels (including 0) and we set no speed restrictions on the kit. This is controlled by the display setting. If you want to program your own settings and even try to “Hot-Rod” your own kit, then you can do so, with the programming lead that we sell here on the site.

Bafang 48V 750W BBS02 Ebike Kit Warranty

EM3ev offer a solid 1-year warranty (not a flaky 3-month warranty like some) on all our products (unless specifically and clearly stated otherwise). We have have local support in the USA, Australia, UK and Ireland. Customers can send problem motors parts to our local support for repair if the issue cannot be resolved remotely.

So, please consider that when making your comparison between suppliers and also consider that we have been supplying ebike parts (and also manufacturing batteries, in our own factory) for around 5 years. EM3ev is operated by an Engineer that actually understands what we sell. EM3ev was built on the back of happy customers and good products, not self-promotion, hype and paid bloggers!
