HOW TO MAKE ANY MID DRIVE EBIKE REALLY QUICK!!! | BAFANG ULTRA + PHASERUNNER

[@diggy2107]

Andy ! I just want to tell you that I have been watching your videos for a long time and I just finished my first e-bike a bafang mid drive, thank you for all your videos and you inspired me all along until I finally saved enough money!!!!

[@jimhofoss9982]

fantastic! glad you figured out all the programming, glad to have this controller reviewed, compact, powerful, high voltage, and nice design. I used a Nuvinci 360 gearless autoshift rear wheel with an older bafang 750 watt middrive, on a full suspension bike. Only a 10ah/48 volt lithium battery. With a 46 tooth on the crank, it will take you up mountain faces with ease, torque to back wheel astounding. Any middrive enthusiast should try a Nuvinci hub, they even make a higher ratio now, 380, I think. They work so well with middrives....simple one chainline, low maintenance. Even can get the autoshift module, which changes ratio as wheel speed increases...and you get a compact bar control up and down switch to select your cadence preferance. Slick! Cheers!

[@toyotaprius79]

I just have a bone stock dahon from 2012. I've always thought of where to buy a Nuvinci gearbox. No bikes in Ireland are sold with it, eBike selection is not as great elsewhere in europe. Now, the mad engineer in me is saying to put together a Nuvinci hub, with 5 chain speeds, a mid-drive motor and a front hub motor. It would be like a moped/prius

[@jimhofoss9982]

_B -Lowe_ You can order the nuvinci hub, or built wheel, online. There is adequate ratio change in the hub, that only one chainline is needed, thats the beauty of them! cheers!

[@ShadowRifft]

@@toyotaprius79 I'd be set with a SingleSpeed-CarbonFiberBelt/RoadBike, Nuvinci, MidDrive + front hub motor. Range(Big) type of battery for sure with Regen. 😎

[@SnowySnugglekins]

Love your videos and this kit! I picked one up and on the third ride out I didn't seat the battery properly, which came flying out the first bump I went over and I totalled it. Full warning to anyone getting an ebike, double check your battery is in properly every time. That's a thousand dollar mistake you don't wanna make!

[@traderfjp]

I keep a zip tie around my battery for insurance.

[@chillchilli2671]

i used zipties andratchet straps at first and held it inbetween my legs while using throttle only. I couldnt pedal at all. I ended up getting a back carrier and bolting the battery to that. its very stable now i can pedal and throttle, going 50km+

[@GrinTechnologies]

Nice work and persistence Andy getting this running. As far as the throttle pickup off the line goes, by default the ramp limits in the Cycle Analyst will be limiting things rather than the Phaserunner ramping. The CA's default throttle output up ramp of 2 V/sec is fine and snappy for normal ebike controllers that have a motor PWM throttle where the entire span from zero to max power happens over a small voltage range, but on a Phaserunner or other controller with a torque throttle this translates into like 1.5 seconds for the motor to go from zero to full torque. You can should increase the CA3's throttle output up ramp rate to like 10V/sec if you want it to go full torque with no noticeable ramp up delay.

[@joeows6537]

You kept mentioning a "Pscho-Analyst" and therefore I've avoided getting a ebike, cause who needs the grief right.... now that I know that it's a CYCLE analyst, i will seriously re-examine that! Love your videos my brother.... stay safe!

[@46B3x2you]

This might sound silly, but having thumb throttles can lead to problems with your thumbs. I have thumb throttles on all my e-bikes I have a dual motor e-bike with two thumb throttles. Now my thumbs don't work quit right. We take for granted that we don't really use our thumbs for much other than supporting all the other lesser fingers, but, without a thumb on either hand.., you would be handicapped. Having two thumb throttles, one for each motor, I found over time that my thumbs get stuck and don't move freely. When I try to do delicate work, my thumb will be stuck, and then spring in to action... (No fooling Here! ). I can put either thumb, from either hand; because I use two throttles, into the palm of my hand and the joint will click. When I take it out of the palm of my hand it will release the potential energy. I was trying to do some delicate work on some small parts for putting directional turn signals on a new build and sent small parts flying across the room when my thumb decided to kick them off. You wouldn't think that this could be possible, but when you're grabbing on to the handlebars for stability, and releasing that grip to increase speed continuously...You're using your thumbs in a way that they are not meant to be used. I know what everyone is thinking... I use both my thumbs to shift with trigger shifters. With an e-bike it's a constant use of very little pressure needed to maintain the speed on top of using a lot of strength to avoid obstacles for grip. I never would have seen it coming and it's a real pain in the ass. You can laugh at me now, but if you use thumb throttles; and I love them, on rough terrain, or even road use, you'll know what I'm talking about over time. I don't think it's just me because both thumbs were affected at the same time. I hope this is helpful... If not a source of laughter for some non-believers. Love the videos as always. You're the best. Get some sleep!

[@pharrohku5922]

I know what your talking about with the thumb getting tired and there is a FIX for that. I have tried switching the Thumb throttle around and using one of your fingers on it in the other direction works well

FINALLY somebody on KZbin giving straight, and correct info. I personally have been running a Bafang BBSHD with a Phaserunner @70v/ 50A. My bike is strictly street use stretch cruiser(basman frame with tank) and weighs 90lbs. I can still reach 45MPH+ using a Sturmey Archer 3 spd IGH. However, be aware you need large amp hours(ah) if you expect any decent range. I run dual 12.5ah packs in parallel. Kudos on the setup!

[@darrellrichards2326]

Hi Andy have you been able to research which Yamaha spider will work with our ultra motors. I have a fat bike and I had to reduce to BCD 130 40T Raceface . With a fat bike so more off set would be great. the Yamaha makes a 6mm off set spider. not sure if its compatible. currently called FatSix SDURO motor spider. but they also make the PW-X spider with less off set maybe 3mm. Do you know which one would fit the current Bafang spline. Thanks

Hi, I just took it out completely 😁 and wired this controller to the motor directly. You can do this with any motor.

[@kransurfing]

Looks good! Are you running w/ the hall sensor or still in sensorless mode? If the latter, get a few HIGO connectors and wire up the hall wires to the cycle analyst, you'd have much better results with torque ramp up and the rest; from what I've seen.

[@andykirby]

See the last video, this motor does not have hall wires ... yes I know! They use a special IC on the control board so your only option when using another controller is sensorless. It’s still wheelies, startup torque is ok.
