In terms of clearance, no. I installed the chainring so its on the outside of the chainring spider. Because I programmed the M620 to pull upto 750w (20amps at 120NM of torque), the chain life was comparable to 250w mainstream ebike motors like Bosch, Shimano etc. As soon as you revert the motor back to 1500w (30amps at 160NM of torque), you are more prone to snapping the chain when suddenly shifting. My E55 uses a 36t chainring, whereas my E22 uses (now) a 34t chainring. Hope this helps👍🏿
So thanks for the awesome instructions. Do you keep those spacers/washers in the right order when the crank arms are off for a few days? I know mine would be random install ever after.
The lockring can only tighten onto the motor/spider/chainring one way. So you shouldn't run into that problem. As for the bolts which secure the cranks, it doesn't matter which one goes into which crank arm. The bolts which secure the chainring onto the spider are designed to go in one way. And any washers are of the same width/height/circumference/depth. So it doesn't matter which orientation you place them in. Just make sure you use grease when installing to prevent any unwanted creaking👍🏿
Many thanks for your kind words. I'm not sure if the Raceface crank will work with a fatbike setup as the Q-factor is wider on fatbike specific ISIS cranks. It it helps, I can have a search to see which aftermarket cranks will work on a M620 fatbike setup. Bare with me, I'll get back to you shortly 👍🏿
Apologies for the delay. At this point, I have only found the Miranda Delta ISIS Fatbike cranks in 170mm. I'll keep my eyes open if I see other cranks 👍🏿
Hello, Neeko so im planning to build a defung E10 (i think max front travel is 150mm) so with this adapter am I be able to achieve the correct chain line of 52mm for a boost frame spacing? im just curious what frame do you have and what front fork travel you are running? Thanks in advance 🙏🏻
Hi there, My E10v1 (now), is running a 170mm travel Rockshox Zeb 29er fork with a 44mm offset. Previously, it was running a 180mm travel Rockshox Lyrik rc fork 27.5 with a 44mm offset. Essentially, the bike retains near enough the same geometry. But it has gained a greater roll over in terms of speed. My E10v2 (which I'll be debuting soon), will run a 160 fork in a 44mm offset 29er. Basically, Dengfu have requested that I build one closer to the stock travel numbers they have outlined on their website. But essentially, the Dengfu E10 can be ran with a fork travel of 150-170 29er or 160-180 27.5 (from my experience). Keep a watchful eye on upcoming content as I'll be delving into this in upcoming videos. Thanks for your comment 👍🏿
Love your videos! They've been super helpful! Do you find that the 38t chainring is the sweet spot for an 11spd? I have a 42t but wondering if maybe I went too big... Is the tool you're using for the bottom bracket a 44mm 16t?
Apologies for the delay. Currently, I'm running 32t chainrings on both my E10 and E22. You can use a 38t chainring (provided the chainring is optimised for an 11spd chain). But finding a 38t 130bcd chainring is difficult. Hence, why the Christini chainring/spider is so helpful. The tool I used was a 44/16 shimano bb tool. I do have a better tool which is 'YC-29BB'. Use Google and you'll see what tool is better for removing the lockring for both the M500/M600/M510/M620. Thanks for your comment 👍🏿
@@neekodevinchi Thanks for the detailed response! I have the Christini Spider ordered! What do you like most about a 32t? This is all very new to me :D
The primary reason for me using a 32t chainring is to give the motor a mechanical advantage, without excessively using more power from the motor/battery. Basically, I can run lower levels of assist, to achieve feats which would be reserved for higher levels of assist. This results in the E22 becoming more economical in terms of range/efficiency/battery consumption etc. Naturally, the 11/50t cassette 12spd drivetrain aids with this as well. In addition, the Christini 104bcd spider adapter allows you to run from 32t - 44t. So essentially, the adapter gives you more options in terms of chainring sizes. Personally, I prefer the 32t chainring. However, there are others who prefer the 38t for the speed advantage it offers. Hope this helps but feel free to check out the E22 Frameset thread on emtb forums 👍🏿
@@neekodevinchi Again, thanks for the thoughtful response! I'm sure I'll have more questions but this and your other videos have already given me a wealth of knowledge!
Sorry Ruban, the Bosch spider/chainring doesn't fit on the M620. The splines do look similar. But the diameter of the Bosch chainring is a bit smaller compared to the Bafang Ultra spider/chainring. Thanks for your comment 👍🏿
Since making this video, I've used the chainring adapter on my E22. For my style of riding, its quintessential and a must have. Thanks for the comment 👍🏿
They have different offsets. I know M600 spider requires a 3mm spacer to make it works on m620 motor. It means M620 spider on M600 motor will shift the chainring 3 mm outside and will maintain not straight chain line for single cog or not ideal chain line for cassette. It also means the M620 spider on M600 motor will take 3 mm on the spider nut treads so the nut will be shifter 3 mm outside too and probably will not be engaged properly with the threads. So I would say it does not fit M600 motor.
I use the same spider on my bafang M620. I can notice a mechanical advantage from the motor with a 34t chainring. Looking good Neeko
Good to know dude. Appreciate the feedback and comment 👍🏿
I see you got rid of the spacers with this new spider. Exact info I was looking for. Chain looks very close to the chain stay. Ever have any issues?

Just like to say thank you for your video and the hook up with Christine bikes do you know that race face cranks will fit the m620 for a fat bike

@@neekodevinchi I have the same question as well. Did you ever figure it out?
Apologies for the delay. At this point, I have only found the Miranda Delta ISIS Fatbike cranks in 170mm.

Can you use the Bosch chainring with the Bafang Ultra Neeko? Cant wait for the next video ✌🏽

I've heard about these adapters. Do you think it's worth the $100 asking price Neeko?

Thanks for the comment 👍🏿
That spider fits the M600 as well correct?
It can. But the M600 uses a 104bcd spider adapter stock. The M620 comes with a 130bcd spider adapter as stock 👍🏿
