Re: I did it - I launched my Bafang Max based ebike! Also selling Bafang max spares !

Looks plenty sturdy and equipped with nice features. The Ti is a nice touch and if fabbed in Beantown that is a bonus harkening back to the old days of Fat Chance/Merlin/One Off. Good luck with your venture!

Re: 29" e-bike for commuting - rear hub motor or TSDZ2 ?

I own both a TSDZ2 that I have mounted on my steel 29"er mtb and I have a couple of front hub motor 700c drop bar bikes. In my experience either system would be more than enough to do your route with a 10ah battery averaging 15mph. The one thing I would say though is that the hub motor system is way...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

Thanks for the breakdown Wayne it was very concise and informative. In fact if you don't mind I am going to copy and paste it to my contact in Bafang to see if it gets any response. He is in charge of international sales and not an engineer but hopefully he will get the idea that without some system...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

I had high hopes for the M600 and worked with another frame designer in China to get the geo the way I wanted it but now that that is settled I am not going forward with production. I really require a throttle and to me it should be an integral feature on any eBike. Not so that one can just ride aro...

Re: Bigger tire in front?

It is my experience that a narrowish tire on a wider rim has as much effect for running lower psi reliably than a wider tire on a narrow rim. My preferred setup for the front is a 2.3 tire on an i35 rim and although I use 700c the same theory should apply to either 27.5 or 26". With this combo I can...

Re: Throttle on drop bar

Simplest solution I have found for throttle use with drop bars is this: https://www.ebikes.ca/shop/electric-bicycle-parts/throttles/handle-bob.html I agree that a cruise control function works great and use it all the time. Easy to override by either a blip of the throttle or my regen button. Also u...

Looks good Wayne, glad it all has come together and you are in a good place for “test” rides.

Your first description of the TA sounded good as push for power is what I seek also as well as a throttle. Looking forward to some more reports as there still is little out there on the M600.

It is my experience that a 250w “rated” system is not going to be much help on hills as noted above.

Re: Feiwel 27.5+ Bafang M600 Dual suspension emoutain bike

Geometry looks pretty shaky. Long chain stays and steep head tube would be deal breakers for me. Also I am not as much of a fan of integrated batteries as most seem to be due to down the road adaptability to new battery structure.

I forgot to mention that on my eMtb I have ChiBon rims front and rear with WTB TCS tires and have not had any issues with them getting tires on and off. One is a 650b i35 rim and the other is an i35 700c. You really can't blame the tire in this instance I feel. I would wager that any tubeless ready ...

I use TCS tires on all my bikes, but I do also use their rims, and as your mechanic pointed out he had never seen anything this bad before and there are way more WTB tires in the market p...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

There is a Can Bus protocol imbedded in the BMS for the M600. It probably has an affect on the throttle function. This is a new move by Bafang to come into line with the manufactured products by the EU manufacturers. However, unlike all Bafang products that have come before that are DIY user friendl...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

I see the M600 as the anti EU motor. Yeah, the Levo gets lots of love but it is not at all perfect and it LACKS A THROTTLE which is important to some of us. Not so that we can go thumbing the thing exclusively but because it is a handy item to have on board and the fact that the EU regs have somehow...
