Build has been brilliant! Took a little bit to get the Sabvoton dialed in, as well as the brakes. Had a bad rear brake that we bled a few times and still was mushy. They replaced it. And once we swapped out the brake pads it was way better. The headset bearing has some play to it so thats on our...

thanks @MDG ! Yup, it's been awesome. All their friends want them to build ones for them now.

Thanks @Eastwood! Boys love the bike. All their buddies want them to build one for them now. Yea I was able to get the sabvoton mostly sorted.

So I think I sorta understand these assist modes better now. - If I set my controller DC current to 30a, and boost to 60a, there is a considerable drop-off in torque when I switch from level 3 to levels 4 and 5. - If I set my controller DC current to 60a and boost to 60a, there is still a...

Thanks @E-HP. I set it down to 30/60. Weirdly enough the 5 assist modes are now screwy. In mode 3 it's almost as fast as before, but when I set to 4 or 5 it the speed immediately reduces. Baffled. Somebody told me I should only set to 3 assist modes anyway, so I will try that.

thanks for the quick reply. yea sorry for the typo. I put V instead of A for those... just corrected in the OP! ok so I will turn the DC current and peak down to 30A and 60A. We these default settings at 80A, would that actually provide more power, or was it just draining the battery and...

Hey all - been posting the progress on my first enduro build with my boys over here First Enduro Build For My Boys (14 & 12) Long story short, build came out awesome. Boys thrilled. Now just trying to understand how to program and tune the 7280. Documentation is crap. I bought from NBPower and...

and thats a wrap. bike complete! very happy boys. now I need to figure out how to tune the sabvoton SVMC7280 controller. I had a cut outs already. and more importantly, the speed limiter on the UKC1 display doesnt work. I need to figure out how to add a speed limit on the controller. I know...

thanks for the tip on the tracker. got one coming in tmrw!

The info NBP told me was the Qs205 v2 was rated as a 3kw and the Qs205 v3 was rated as 5kw. Dont know the technical difference of the two.

the past couple weeks build.

@nicobie its been a great project with them ❤️. we've had so much fun working on something different every night and them excited for whatever new part comes.

thx all! should have first ride today. the rear fender is a mucky nutz tire hugger. some shots of last night putting in the battery and first hall test. we did have an issue with the charger fuse popping when we first plugged it in. blew the second fuse too and one of the three prongs is...

coming together. thx for all the help @amberwolf

coming together! you guys have any recommendations on a charger for a 72v 20ah battery? also does the Sabvoton have a connector for brake lights and headlight, or do you have to wire them? thx for all the help.
