Re: Dengfu E06 build.

sick! the twist lacing gets me all excited like it did back in the 90s - i grew up riding during the boutique cnc era when that was somewhat common. actually, i have over 30 bikes from that era in the collection

phenomenal job on the build

Re: What are the best ways to build a two wheel hub mounts e-bike?

you know, i was thinking about it some more and i am inclined to think you are probably right. nowadays with fat bikes and plus sized tires plus tubeless allowing you to drop the pressure way down the need for a 2wd may be a thing of the past in most situations. people ride fats under human power on...

Re: Replacement for CS6500 HyperGlide?

I had actually never heard of bikes island, There's all sorts of great deals on there, What's crazy is some of them are like 10-year-olds models That they strip the forks from, Some are blems, some are entire runs of defective products (they have a pretty nice looking fat bike frame in plentiful sup...

Re: Replacement for CS6500 HyperGlide?

i just looked that bike up, i am familiar with motobecane and gravity being the house brands for bikes direct but did not know the exact model its actually a REALLY nice bike, chances are they spec'd that cassette for weight savings and close ratio shifting always being a bit crisper. the one you ch...

Re: Replacement for CS6500 HyperGlide?

That's a road bike cassette, but since you have an xtr rear You should be able to clear a much larger cassette If you want to. assuming its the m952 or m960 if its 9 speed, it should clear AT LEAST 34-36t up top, respectively so the ones markz mentioned are all good bets. I find the shifting perform...

Re: What are the best ways to build a two wheel hub mounts e-bike?

2wd seems like a good option, really the most difficult part for me would be figuring out the ideal throttle combo. ive been doing left throttle and running a 1x drivetrain with the shifter on the right. i dont know that i would want power going to both wheels simultaneously at all times at the the ...

Re: Kids 500w fun bike keeps cutting out

just speculation, but it doesn't sound as if the controller is bad, more like the battery is sagging hard enough under load to trigger the LVC on the controller. without knowing what the cutoff voltage is set to it could just be assumed that it is higher than whatever bms is on the pack. assuming it...

Re: Kids 500w fun bike keeps cutting out

not knowing the brand i would guess 24, or maybe 36v. my theory would only apply to batteries that actually have a bms, so if its one with a sealed lead acid battery it could be another story...that being said, even if it is it is possible it has some type of lvc in the controller or something. As l...

Re: Kids 500w fun bike keeps cutting out

sounds like low-voltage cut out, chances are the battery is sagging when he's getting on it pretty hard And the BMS is cutting power

I can absolutely believe that, This would be for my own bike so I'm not too worried and can usually spot the telltale signs of the pack going out of balance Just based on the performance/longevity characteristics So more than likely I'll catch it before anything becomes too serious, As for the cheap...

Re: no bms ok for 10s1p minimalist build?

Good answers, thank you. Looks like balancing leads will be a necessity which isn't a huge deal. For this application I can potentially go to 12s, So perhaps I can even do 2s balance lead set up To keep things a bit more precise. Not going to be hammering the cells too hard, I think they are rated f...

Re: no bms ok for 10s1p minimalist build?

Sounds like I'm good to go, thank you would consider alarm but at the most i will be pulling 15 amps and have Lvc on the controller set around 31v and volts showing on the display at all times. I feel like there's minimal chance of a set up like this going out of balance being used the way it will b...

Re: What are the best ways to build a two wheel hub mounts e-bike?

Chiming in here as I have recent experience with this, albeit less experience than others. As far as 4 inch tires that would be considered actual fat bike territory and as a result you'll be dealing with some weird drop out spacings That someone limit the motor choices. There will be an assortment o...

hi all, Just getting ready to make a couple 1p Micro packs with Samsung 40t 21700 For a stealth build that I would typically use RC battery packs for. as I am trying to keep the form factor as small as possible I was looking to run these with no BMS. In my mind, it's OK, I'm not doing it for a custo...

just to take things a step further than my previous question, i noticed many of the entry to mid level fat bikes on the market using hubs from bafang, shengyi and now even mac on some juiced iirc. Presumably most will get minimal real off road use past dirt paths etc But do you figure hubs hold up a...

Re: a quick blast through the snow on a parts bin family hauler

The bomber holds up fairly well and has pretty beefy dropouts, But given the opportunity I'll probably go for some thing with slightly beefier stanchions since i think under full load they are flexing a bit and keeping me from achieving full travel. all in all, I can't complain As for the most part ...

Re: 1000w upgrade ? or new kit ?

you can definitely push it harder, get a decent 52v battery, a controller upgrade can be had fairly cheap and even if you decide you still want a different motor later on at least the battery can be used on that. make sure it has a decent BMS as a lot of the hailong style packs and the like have 20-...

Re: Geared Hub Motor Quality

You know, that's pretty much along the lines of what I was thinking but every once in a while I'll see like a guy running a Q 100 or something on a mtb So I just figured maybe they knew something I didn't. Agree on the mid drive, or massively powerful DD for flat fire roads and things
