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!

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...

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...

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...

Good timing on this capacity test as I just received a 14s3p battery with them on board.

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...

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. Have you checked into this: https://www.ebikes.ca/shop/electric-bicycle-kits/bafang-g310-311/front-g311-kit-advanced-pas.html Geared, light and if run as a 36v/15A will give you a relatively non stre...

A little more evolved geo in the pipeline

It is make by Risen bicycle?

Yes, Risen bicycle wants to not just make bikes that fit e motors but are interested in their evolution as well.

A little more evolved geo in the pipeline

UN3480 guidelines for hazardous goods regulate the shipment of Li batteries internationally.

Having unpacked shipments of multiple high Ah batteries from China they were nothing more than wrapped in these
In a sturdy cardboard box.

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 ...

Are you sure the problem is with the WTB TCS tire or the BSD of the Dengfu, or whoever they got it from, CF rim? 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...

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...

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...

The new silent killer in our streets: Electric bikes may be green and trendy, but last week they claimed their first British victim and experts fear there will be many more:

Lest we ever forget....

Although I try to keep up here this may or may not have been featured: https://www.dailymail.co.uk/news/article-6171963/Electric-bikes-green-trendy-week-claimed-British-victim.html It seems that now the media is playing the fear card in order to better align with the politicians who are holding all ...

Got it direct from Bafang that the motor is good for 52v as that is what I want to run. Nice that it is quiet. Quiet is good.

Nice and light but that will be negated the first mud patch you go through and the system gets loaded up due to it's placement and as far as I can tell become ineffective at the same time? Certainly won't work here in Oregon for the upcoming wet season fast approaching. Should work ok in dry climate...

Holes in the bottom of a box are like escape hatches for any small parts that might want to escape, hope that's not the case. Why the shipping company would send the thing to Tennessee is beyond me and lucky you didn't get a tariff slapped on it there. Did they ever send you a drawing of the frame? ...

is it open source alu frames? can be bought where? Yes, open source. Probably a few months out on production however. Depends on how well the proto rides as we are working with then to have it inline with up to date geo which wasn’t their original plan. They are also a carbon facility and after the...

Aluminum FS prototype M600 frame on its way to t4/t6 heat treatment. Won’t be the lightest frame but good enough to confirm the geo and go from there. 3C56E941-B3F6-4B0F-B6C9-BA14ED7F490D.jpeg Put battery company together with Bafang for BMS protocols and CAN today. The frame as shown is for the Baf...

Progress with using a different manufacturer for an M600 based frameset. Actually two, a fs and a ht. FS proto finalized geo so it’s first in line. Proto frames will be non integrated batteries to accommodate the 15ah 2170 battery being developed along side. Should have all the parts and pieces toge...
