Thank you so much for doing this SPMTB! So informative and concise. Great job SPMTB!!

[@motopaulo]

Thank you for this detailed walkthrough (and special thanks for explaining the dropper post routing). This is excellent technical storytelling!

[@SimplePleasuresMTB]

Well thank you. Glad I could help 👍🏻

Did you find a flat washer ty9e spacer when cleaning it?

[@tomdykhouse5665]

@@christophersmith2102 There was a “shim”/washer between the case cover and the outer race of the bearing on the crank input shaft. Not sure if that’s what you are referring to. Was maybe.005” thick.

[@christophersmith2102]

@tomdykhouse5665 yes I finally found where the location of it.. I laid it in the controller side and use a few dabs of greese to hole it in place as I turned the control side over onto the gear case side

[@steve_main]

I'm going to be pulling my Befang Ultra in the next few days to do the JD grease on it. Scared to crack it open but really want to quiet my motor! Perfect video to show me what to expect!

[@SimplePleasuresMTB]

Just be careful on the fine wiring. It’s pretty easy.🤙🏻

[@geekverve]

I'm sure the red and black wires are power from the battery. Thanks for showing us those innards.

[@SimplePleasuresMTB]

Thank you

[@JKL...2025]

You can get a manual from Bafang, it has the breakdown for the wire colors.

[@lukefarmer5391]

Sorry I did not catch why your opening the case, is the motor starting to make noises or getting noisy? Also why that particular grease, I didn’t catch that either? Thanks.

[@SimplePleasuresMTB]

Out of curiosity and requests to do it. I have always had a rattle noise that I wanted to track down also. The choice of grease was recommended to me from a few on some emtb forums. I did some research and decided to give it a try. Part 2 should be available to view at 10am tomorrow.

[@BramBiesiekierski]

Nice look at the ultra. Do you know, or are able to measure the offset of the chain ring adapter? And how do you find the 36t chainring. Im about to build up a dengfu e22 / ultra eMTB. And am collecting parts for it now while I wait for delivery.

[@kcretired1032]

Thank you for showing how to corn grease the Bafang. Hadn't seen Sondors rockstar until your vid. I looked and it is $3500, and it has an aluminum frame and weighs 80lbs and has a 750 watt motor. Is this the M600 bafang? You have the bafang M620. I have been considering the Luna Z1 or the X2, both carbon fiber. The Z1 comes with Bafang Ultra M620, the X2 comes with Bafang M600, however is upgradeable to V2 Ludricous Controller which puts out 2500watts versus 750watts. Considering your experience with the bafang motor which of these two would you pick?

[@SimplePleasuresMTB]

Personally I’d pick the X2, but never personally rode one. The Sondors Rockstar is equipped with the m620 750w motor. It’s heavy, it comes with less than desirable components, customer service is hit or miss. The Luna X2 would be what I’d pick between the 3 choices, I only have the Rockstar because it was given to me to test out and show what it could be capable of. It’s definitely capable with upgrades and I honestly love it. But I’m ready for something a bit lighter. Thanks for watching 🤙🏻

[@kcretired1032]

@@SimplePleasuresMTB Thank you, the X2 with the V2 Ludricous Controller upgrade for the same price as the Z1, also the X2 with the bafang M600 will except 48V, 52V and 72V batteries. Apprecitate your all your work, help, and sharing.

[@SimplePleasuresMTB]

@@kcretired1032 yeah I rode with a guy that had the X2 and he put the ZEB fork and a few other goods on it and it had the same range as the Rockstar at a lighter weight package. The X1 needs more range, the Z1 has some cheaper suspension (DNM) on it. I’d go with the X2🤙🏻

[@kcretired1032]

@@SimplePleasuresMTB Thank you, just got back from TREK store, test rode a RAIL, wow pedal assist was magic, first time. The cheapest RAIL aluminum frame $5k, with carbon frame $7k, ouch. Trek does not sell bikes with Throttles, Only PAS pedal assist. Told them about Luna, got a pitch about TREK quality and maintenance, they are right I have owned Treks, But for the price, and No throttle, and they use Bosch motors?

[@SimplePleasuresMTB]

@@kcretired1032 Trek rail is a great bike, I have a Trek downhill bike and Trek makes some of the best. But yes, you are going to pay big time😎If I could afford it, I’d get the Rail, couple friends have them and they are great, but max speed is 20 mph on the Trek, the Luna has more power and range, costs a lot less and with some upgrades will be more bang for your buck. If money was no object I’d go Trek, but best bang for the Buck the Luna is awesome. Both are great

[@stephendouglas6328]

This is fantastic. I'll be putting a dropper post on my bike when it comes. Is yours cable actuated or hydraulic?

[@SimplePleasuresMTB]

Cable

[@peterthomson6161]

Looks like the motor is waterproof enough to hose off.

[@SimplePleasuresMTB]

It is, I’ve done it many times. 👍🏻

[@WestCanaanTim]

Thanks for another top-notch video! Very precise instructions and exactly what I was looking for to regrease my Bafang M620 motor. Ha, my other hobby too that I'm actually getting back into this year is kayak fishing. Looking forward to getting my new Old Town Autopilot 136 in the water..

@@symbiketour4704 I don’t have any…I only have the stock cranks. There are other companies but more expensive. Just look for Delta style cranks online, I’m sure you could find the Miranda cranks somewhere besides Amazon, maybe try EBay? Just looked, they are $102 plus $15 shipping, little pricey I’d say

[@christophersmith2102]

There is a flat spacer type washer .. I found when cleaning out old grease . Can't remember it's location . I think it sets on on controller side between the 2 sides on . And is on crank stem

[@SimplePleasuresMTB]

It’s not the washer that goes on the axle spline? Before the snap ring?

[@laplantemichel709]

How much mileage did you have on it at the time of this video .Was there any wear ? Thanks

[@laplantemichel709]

A friend of mine has 12000kms on his M620 and the gear that meshes with the rotor's pinion gear is gone no more teeth and the inside of his motor is really dirty wondering if the gasket did it's job ?

[@SimplePleasuresMTB]

I want to say around 500? Miles. Mine had little to no wear that I could visibly see. My friend that had over 2000 miles his main pinion gear was very worn, had to replace it. His bike had very little to no grease in it from factory. Very loud motor. Once the gear was replaced and new grease it was very quiet.

[@jaydouglas393]

Hi would you answer what is the problem with the wheels on the elite sondors bikes. You have extra what are they hubs you called them. Did you get replacement wheels from sondors? I’m scared to buy the elite LX , or Cruiser because I keep seeing people have bearings go bad or the wheel locks up. Should I be worried should I trust these are well made and built to last. What would you suggest one do to prevent the wheels going bad?

[@SimplePleasuresMTB]

The wheels on the LX and Cruiser are different from the Rockstar. They are wider I believe for the fat tires they are running. I’m not sure of the issues on those hubs…but it could be the same heavily greased freehub pawls sticking like we’ve seen on the Rockstar’s. Everyone has had different experiences, good and bad. I really have no experience on those LX or Cruisers though.

[@robcoastalga8279]

Thanks for the vid! Reusable missing links by KMC are the shiz. Plus you don't need that link separator or to position chain link in top position and brake pedal combo to secure. Also not supposed to reuse those missing links that require the tool. Chain making noise it's under lubricated/nasty and if it's been going on long prob worn which could mean the infamous and incorrectly labeled "stretch". Which slowly ruins your cassette leading to chain skip and sad teeth.

[@shawnsangha]

do you still have a hub for sale?

[@SimplePleasuresMTB]

I don’t have any for sale at the moment, but I’d suggest this one, it’s what I’m currently running, it’s got 500+ trouble free miles so far. You would need to have your rear wheel rebuilt. www.ebay.com/itm/265642389944?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=SI4mMLnDTx-&sssrc=2349624&ssuid=KI4hmpu3T7e&var=&widget_ver=artemis&media=COPY

Can I schedule an appointment. My bike has 700 miles and it’s sounding like a chainsaw

[@SimplePleasuresMTB]

Yeah, your motor needs it

[@michaeldeliseo553]

Do you know of a company that can rebuild a Sondors LX Bafang M620? Mine is recently broken.

[@SimplePleasuresMTB]

You can order parts from www.greenbikekit.com just put in m620 in the search bar and they have everything to completely rebuild the motor

[@JKL...2025]

It's a g510 motor, with associated hardware e.g., isis spline it's known as m620.

[@kenharvey9714]

I've just bought a bike with this very same motor. I was previously riding a 20 inch fat tire folding bike with 750 watt Bafang hub motor with 48 volt 16ah battery. There is a steep hill (tarmacked road) which I regularly ride up. The old bike gets me up it comfortably at 14 mph in level 3. The new bike with this 1000 watt mid drive and 48 volt 17.5 ah battery, only manages to get me up it at 12 mph in level 5 in sport mode, while putting in quite a bit of effort pedalling! I find the range of this bike also only around 18 miles whilst riding in only low pedal assist modes, when I can get around 30 miles out of the old bike. Do I have a problem here? I find it hard to believe that the new bike is so bad. The 750 watt hub motor is leaving the new bike for dead. I'm so disappointed!

[@SimplePleasuresMTB]

I’m not sure, I do know that depending on where the motor came from some are better than others (from what I’ve read on the forums) it could have a weak battery maybe?

[@kenharvey9714]

@@SimplePleasuresMTB Thanks for the reply. I'm thinking it must be the battery. I've had a 250 watt mid drive in the past that had more go than this thing! This is the bike in question. Mine is black.

[@giuliom8520]

Probably cheaper to just buy a wheel with e-bike hub already installed, rather than trying to fit a new hub into an old wheel.

[@SimplePleasuresMTB]

A super boost hub with 36, 13 gauge spokes and an internal rim width of 40mm…I kinda want to retain that but I got that other wheel on standby. So far my wheel is holding up fine. If the ratchet ring is removable, then you can just drop in the $50 Bear Pawls free hub body and your wheel is good as new.
