Need some advice

[Woosh]

I stopped selling the 36V BBS02B 3 years ago, partly because we don't want people derestricting their bikes and get us to fix their motors. We had something like 5 dead BBS02 controllers against one BBS01. That's also why we are reticent to sell components on their own, we just could not be sure what batteries people pair their motors with.
The 48V version BBS02 is even more prone to overheating. The 350W 48V 15A BBS02 was OK.
For 48V systems, I like the TSDZ2 better. You can't destroy a torque sensor motor so easily, whereas you may just push on the throttle when faced with a steep gradient, you instinctively react rightly with the TSDZ2 by shifting your gear.

well most of the 250w stuff we get is 350w thats rebadged anyway, just like all the shimano, brose and bosch motors are all ~600w and badged and limited to 250w. I figured the 500w bafang hub motor would suffice, but there is just so much choice in the hub market and no one seems to recommend bafang hub motors. It's a shame hub motors get trashed so much and everyone rates the bafang mid drives, from what I saw when doing my research and even now doing research on the controllers.

I've ordered a new controller for the bbs02 and i'll limit the amps to 18A and see how I get on, but I think I might just pass the bafang kit on (my dads after a kit for fair weather usage) and get a hub kit for myself. I might be really handy when it comes to repair and maintenance but that doesn't mean I want to be doing it all the time.

Still here, I thought you were going.

Bye.

Turns out this forum isn't too bad with you set to ignore.

Good job you don't see my messages then eh?

DUH.

To the OP, I’d stick with the bbs02.

Replace with an external controller - you can use this for a hub solution if you change your mind later

upgrade your gears to a 9 speed XTR shifter, optislick cables. Set up with a tight derailler, your gear changes even under load will be smooth

I thought about an external controller, but the pain of going from an integrated set up controller to getting an external controller fitted and waterproofed just seems like way more hassle, and it removes any sort of selling on potential with the BBS02.

I can get smooth gear changes with my sram gear for a whike, but it's keeping them that is the problem, my shimano stuff had to go as I could just never get it smooth for any amount of time.

i have to index my gears alot to keep them running smooth all the time if not it does my head in as it dont like slamming through the gears going 30mph+

it is mostly the b screw on my xx1 that gets loose but lock tight does help but wont hold it forever.

a gear shift sensor will help.
I prefer my 48V TSDZ2 to the BBSes.

Keep your busted controller as a side cover - it’s good for waterproofing if nothing else. You get the chance to hollow out the guts of the controller too, which is a cathartic experience

External controller placement is a problem - I use a hailong downtube battery that allows a controller to be installed within in the battery holder, avoiding water ingress problems.

I have and use a gear sensor. I think it's just the fact that derailleurs are not made for torque electric motors and legs put through them.

Hmmmmm, I have already hollowed out the old controller as I was going to replace the caps with better quality ones, but on getting through the potting compound I found the whole thing had a little bit of fire damage. I also have a battery in a Hailong case, so might look into it a bit more now.

we are going back to hub versus cranks debate.
In fairness, a hub gear would equally stick if you don't take off the pressure on the pedals when changing gear.

I said that to the wife

That's why I'm disappointed Conti discontinued their ebike Division as their motor and gearbox looked like what I imagine the future will be.
