in my opinion this video is one of the best I have seen. The battery build was very clear and straight forward. I built a ebike last year out of my 2014 Devinci with 29 in wheels . A jack model, I put high end commuter tires and a 1000 watt bafang with a48 volt 17.5 ah battery. It bench tested at 99.3 km/h and road tested at my max. so far at 74.3 km/h. that was flat out as hard as i could petal for about two min. lol. 46 tooth on the front. I have about 1300 km on it so far, gone through a chain , two tires, a cassette, and a set of brakes, yes I have pounded this this , but very pleased with the bafang kit. I am craving more power as become more accustomed to the bike . I rarely drive anymore and very inspired by my fellow ebike do it yourselfers. Thanks for your lesson on how to build a battery, I learned alot.

Wow, thank you so much! Truly means a lot to me. Will have to try the BBSHD myself, hopefully this summer. Were you able to pedal at all above 50 km/h? 74 km/h top speed sounds scary haha. The Bafang really is a nice kit to use.

Yes, I am able to pedal at,around, and over 50 km. As one can imagine, you have to be careful in traffic of course, it's the other you got to watch lol. But because I live a little ways out of town I'm able to get onto secondary roads with less traffic and higher speed limits, and that's where this thousand-watt really shines

No words, yet so clear! Congratulations for a job well done!

Very nice engineering... Congrats! As a motorcyclist, I would not recommend positioning the lights side by side as this creates an illusion of being far-away-car to oncoming traffic . Question: I noticed the 6x14 array battery has independent cable routings (balance wires) giving you 3.57V to 50.0V : How does that work? I would assume that this is designed for battery quality correction (?) Is this working with the controller or the charger? Thanks!

@jmcbike

Жыл бұрын

It works with the BMS. The BMS has to know the voltage of each group of parallel cells so it can keep the cell groups relatively in balance during final charging. As an option, you can have an additional separate balance unit that balances faster but still needs the BMS unit for over and under voltage cut out, over temperature etc. One bad or weak cell group will be detected by the BMS and will shut down the whole battery even if the overall battery voltage is acceptable.

@DonnyTerek

Жыл бұрын

Thank you kindly! Since I don't use this e-bike on roads with traffic, I keep these lights pointed quite low to light the road close to me. But I agree that it may look like a car approaching. Yes, the battery has 14 independent cables from each group of cells to monitor the voltage and balance the voltage of the batteries. The BMS (battery management system) board takes care of that, which sits on top of the battery.

Fantastic bike! Couple of questions: 1) You began with a "Mountain Bike". Would this work starting from a "Hybrid-style" bike? (This seems to be a Bottom-Bracket fit question) 2) Was that a 10 speed rear cog you installed? What kind of rear-hub spacing is required for that? 3) This is the _second_ mid-drive ebike conversion video I've seen that goes into great detail about the Speed Sensor, but _totally_ ignores the SHIFT sensor! Please explain. 4) What does the entire bike cost? 5) Why did you re-build the front fork? 6) I noticed you did not show balancing the batteries. Is this un-necessary for an e-bike? Reply appreciated.

@kevinshort3943

10 ай бұрын

Probably work better with a hybrid, due to the spacing around the bottom bracket area. You need a suitable freehub - need to put a wide range cassette on, as you lose all but one chain ring. Not everyone uses a shift sensor. Some people can ride a bike and back off for shifting, or jab the brake insead. The bike looks ancient, with lots of cheap Chinese crap on it, to try and update it. Shop around, prices variry wildly from place to place - try PSWpower It say in the vid - fork service - you are supposed to do that occasionally. The cells would be balanced before assembling into a battery, and it's very long and boring (but not as bad as the battery welding)

Impressive 👍
