Re: reliable middrive for commute?

BBS02 seems like the best bang for the buck right now, few sellers with warehouses in US and EU have them well under 400 shipped The tsdz2 seems to be a love it or hate it situation, with half the people praising it (mostly with the OSF program) and the other half saying it is built like a bag of tu...

Re: Emergency...Is this a good deal?

agreed, no way would i pay the retail. anything with similar specs seems to be 1000+ new though, and it looks to be pretty flawless though i can't determine the condition of the batteries. knowing the place that has it i can assume its probably from spring of 2020 so at best its newish and slightly ...

Emergency...Is this a good deal?

Happened to see this out in front of a local tourist rental place this afternoon. My wife was mentioning a scooter so i just might go for it. from my initial research it looks like anything comparable in terms of specs is typically 1000+ this is pretty clean with barely any wear on it, and most of t...

Re: Kepler Bottom Bracket Friction Drive For Sale (Finally)

Hi Kepler, i tried reaching out to you but i know its a crazy time and you probably don't have any more of these at the moment so for the time being i am going to do a bit of jury rigging my own fixed system just so i can do a bit of test and tune until these become available again...mainly to famil...

Re: Anyone build a chinese carbon hardtail with a mid drive?

definitely interested in the frame, definitely maybe in the Manitou fork but the axle to crown may place the front a bit higher than im looking to go if its the Markhor since it was sized for anywhere up to a 29 iirc and my wife is short. let me toss that around in my head for a bit.

Re: Ebike kit build problem

hard to tell without seeing what controller is if that is indeed the issue but i know sometimes if they have a connector for the switch and it isnt present it defaults to the middle position. Since this is a direct drive motor If it's only getting say 10 amps or something It will be a dog off the li...

Re: Bafang BBSHD 52v 1000w 28a Controller?

yeah, between a full charge and half charge you could be talking 6 volts or so, so 200 watts? maybe 300 with increased sag as the cells deplete. something def seems amiss

what's the advantage to these 52v native setups nowadays? i always ran the regular 48v with both 48 and 52v packs just fine...

Re: pedal assist sensor for press fit bottom bracket

+1, since i have a direct mount chainrings i epoxied a regular PAS ring on that i bored the center from. i think grin has bolt on for regular 64/104 or 58/94 bcd though. the sensor mount will be dependent on the frame but shouldn't be too hard

Beyond 5mph or so the pull is fine, just trying to figure out if i will ever be satisfied with the pull of this thing or if its off to the scrap pile. the bike is literally a slapped together o...

Re: Best bang for the buck DD Rear Hub Kit

is the torque curve on most of these DD motors somewhat proportionate to the amperage? I took my 9c clone off road the other day and it lacked the grunt to get up and go with the 23 amps i was feeding it (48v so around 1kw) when i ran it in the motor simulator it looked like the torque basically dou...

Re: Hub motors with 10mm axles

Good point, i suppose the integrated torque arm would be the giveaway as you're right...if it was a 10mm axle, it would have to be round or the flat would have to be even less

Re: Hub motors with 10mm axles

It is the frames that have 9.5mm dropouts that you need to be aware of. As for the Yescomusa motors I run, they have 10mm axles. :D :bolt: you know, thats what confused me. as someone who wrenches on bikes for a living, we always called them 9x100 or 9x135. I always took is as that the dropouts wer...

Hub motors with 10mm axles

Looking to compile a list of hubs that have 10mm axles and can properly recess into most dropouts without filing. from what i gather from Justins extensive research and documentation, it seems the bafang g310 and the GMAC will properly fit into most bikes without filing. For those of us wanting to c...

Re: Long Travel Fork on Short-Travel Frame?

I may have missed it but didn't see mention of what frame you are using. I have seen headtubes that can not handle the stress of the additional length, as it can basically act as a giant lever, so take that into consideration as well especially if its aluminum A 3kg dirt jump frame.

thanks for the pics, that most definitely looks like a fun, light foundation for a build! let me know what you are looking to get and as long as shipping is not too crazy i think i would be up for it.

Re: DIY Kit, removing limiter

That looks like a slight variation of the typical Voilamart/AW/Jaxpety kits here. The ones here ship with a "Road Legal Wire" which limits top speed to 16mph and peak power output to a claimed 750 watts. On the controllers that have it, its literally just a looped wire with a molex plug If...

I was looking with curiosity at some of these open mold Chinese frames like the BXT and tideace. A lot of them have pressfit bottom brackets but it appears that a few still have threaded BSA cups. I was wondering how these things hold up to the thrashing that some thing like a BBSHD or cyclone mini ...
