i've done nearly 15,000km with my shimano nexus inter3 with a cyclone 1800w mid drive (i also use sick bike parts free wheel an spiders to run high an low chain rings up front, i locked out a derailleur at the rear for chain tension) , best hub out there in my opinion and i've tried a few, sturmey archer 3 speed destroyed itself in about 300km
I just converted a single speed beach cruiser to a mid-engine electric bike. A major challenge since removing the one piece "Ashtabula" crank and installing the Bafang BBS02 electric motor requires adapter bushings to fit snugly inside the bike's hollow 51.3mm bore. Otherwise it is impossible to keep chainline straight and chain from jumping off the chainwheel with the higher torque of motor. Once installed correctly, it is an amazing bike with just a single speed but lots of power assist when needed
Yeah I'd love to see that too, let us know if you come across anything. As far as I've read they're designed for low power and get a little slippery at higher power levels. Their parent company (Fallbrook Technologies) is not far from me here in Austin TX. I've been meaning to go request that they develop a heavy duty version for high power mid drives. I'm under the impression they moved the Nuvinci/Enviolo development to Germany though.
I just learned about internal geared hubs and I thought I should combine this with a mid drive motor, then I thought I wondered if anyone else has done this, so I went looking. The rest is history! except I'm not looking for a custom wheel, I'll be doing that my self, as soon as I get a few test builds under my belt, I've always been of the school, if you want it done right, do it yourself, if you don't know how,,, learn! Just so you know I am building a stealth Bomber ebike, originally I was going to go with a rear hub motor, then I started looking at mid drive motors, I like fat tires, So I was going with 4 inch rear 3 inch front, I still am, but two days ago, I watched a video of a guy who bikes all over the world and he was talking about gearboxes for mountain bikes he talked about Rohloff and Pinion hubs, now I looked at the Rohloff and it starts at about $6,000 US and the Pinion is not far behind, now these of course are made in Europe, so I thought, someone else has to making these, but here in the US they're not called geared boxes but, internal geared hubs, I quickly found Shimano, but there still a little high, but then I found the Sturmey Archer S80 8-Speed Hub, which for about $250.00 I can get everything I need to install the hub on my wheel, except for the spokes of course and I've been watching videos on wheel building even before I got this idea and I have some wheels that I'm going to remove the spokes and rebuild the wheels again and again, until I feel I have a good working knowledge of wheel building. That's how I've always learned new talents and at age 64, I'm not stopping now. Oh and thanks for the informative video, it's just what I was looking for. 🖖😎
Nice! Thanks for watching. Yeah I was thinking about building the wheel myself but I think the last few detailed steps would have been tricky to get right the first time. Shimano also makes a 5 speed IGH specific for eBikes and they say it's heavy duty but keep in mind that the 3 speed hubs are strongest because the planetary gear is fixed to the axle.
After trueing wheels for years, building a wheel isn’t very hard at all with all the good RUclips vids out there. I first did it for a single speed, making it a 2 speed with a Sturmey Archer. So I used a SA 3 for the 1,000 watt diy E- MTB. It works great. It’s small and inexpensive....and nothing protrudes out the side except the nuts.
Nope, 52v x 30A = 1500w peak, no gear sensor, reprogrammed to give consistent power even when ghost pedaling. The Nexus 3 is supposed to be one of the strongest IGH, but we'll see. I definitely would not change gears while the motor is activated though. So far it feels great - stop pedaling, give the motor a second to cut out, then shift - feels a bit like pulling the clutch before shifting on a motorcycle.
I have a BBS02 750w with a Sturmey Archer 5 speed IGH RX-RK5. I have it programmed down. It will be interesting to see how your test goes. I also do not have a gear sensor. Shimano has a 5 speed specifically for ebikes SG-C7000-5D, but it is harder to find and much more expensive. The Nexus 3 speed is much less expensive. Looking forward to your experience.
Awesome, will do - keep us updated with yours as well. I didn't know they made one for eBikes, will have to look into that. I'd imagine it's made for low power systems like the Steps but at least they're heading in the right direction.
I lowered the maximum Amps and lowered the lower levels. I ride mostly in level 1 of 5. My gear 3 pops sometime which is strange because it is suppose to be the strongest gear. I ride a lot in gear 4. I also tend to ride in level 3 and luckily our hills are small. If I remember I lowered the max amps to 15. I can still ride at about 15-20 miles per hour. That is fast enough for me. Read A Hacker’s Guide To Programming The BBS02 & BBSHD Karl Gesslein and other articles By Karl I use Penoff’s program to program my settings. Penoff also has some good programming information.
Yeah bud, I’ve had bikes with IGH on 20” wheels, you might find one to try on a spares or repair shopper bike, or folding bike. Why not build a fixed gear bmx wheel too? Much fun
Yup, so long as it fits in the dropout. Measure the inside of your dropouts or find the O.L.D. (outside locknut dimension) of your current hub - the Nexus 3 O.L.D. is 135mm.
Thanks eBikeaholic, this video is really helpful. Bafang has the GearSensor where it cuts power to the motor when gear change cable is toggle. I don't see you mention it in the video, do you stop pedaling (or stop using the motor), then shift? or it doesn't matter? Edit: I did not read all the comments. So it looks like you manually stop pedaling then shift. I wonder if GearSensor works if we hook it up with the shifter cable.
Yeah I decided not to add the gear sensor for now. I talk a little more about how it feels here: ruclips.net/video/MD1bUpvLJ0Y/видео.html I believe the gear sensor works with either derailleur or IGH.
Hey Austin.. Nice Ive used the Sturmey archer in the past but found it a bit glitchy here n there... But on an other note how do u film the in motion clips ? was really wondering... do u hv someone else tailing u or drone or edited out stick ?
Yeah I haven't tried any of the newer SA hubs but some of them are tricky to get adjusted properly. The Nexus 3 was really simple to setup and adjust so I hope it holds up. In most of these clips I used a Mi Sphere 360 camera and a DIY invisible back bar... still experimenting with it, but how does it look?
How is your wheel holding up? On mine I'm noticing that it slips a little if I push it too hard, pedaling while using throttle. Works perfectly fine with just pedal assist or throttle only.
It's holding up fine, don't get any slips as long as I don't shift while the motor is active. I've been really cautious with it though and mostly stay in 2nd gear... I can see how it might slip if pushing it on 1st or 3rd or shifting while the motor is spinning. Do you think the slipping will grind down the internals?
@@eBikeaholic you know, upon further inspection, it seems that the problem was that my chain wasn't tensioned properly. After adjusting the tension, I had zero problems, and I pushed it pretty hard even on first gear since I like accelerating fast. Seems like its a pretty robust IGH, just no pedaling while shifting. Lol
It'll mostly depend on how much torque you try to pull through the hub and how careful you are when shifting. Make sure there is no load on the hub when shifting (either motor or pedals pulling the chain). I haven't tried an 8 speed yet but as far as I understand it - the 3 speed hubs are significantly stronger because the 2nd gear is planetary. The planetary gear engages directly to the axle so there are less moving parts to get chewed up or worn out. I wouldn't expect a typical 8 speed IGH to last very long at over 750w. If you need the extra gear range consider a Kindernay or Rohloff.
still feels great. I transferred it to a new prototype bike but still 1500w Bafang Ultra. The shift sensor is on there now as a fail-safe but still avoid shifting under load. I mostly start in 2nd gear then quickly bump to 3rd for cruising. I'm starting to notice if I'm careless when downshifting back to 2nd when fully stopped at a light etc. - it gives an extra click when it changes gears while launching on throttle at the green light... so prob best to avoid that too.
@@escargoux not unless you custom mount the hub like a mid drive which isn't worth it, hubs are direct drive single speed only, that's why they suck but for in extremely high power versions like 5000watt plus
yeah I'm pretty sure it's compatible but I haven't tried it yet. Pausing a second before shifting hasn't bothered me but I'll probably try the sensor eventually.
Does anyone have any links to the articles comparing or commenting on IGH for ebike conversions? I have a cyc pro coming and was going to put it on my old pug, but I think I might instead put it on my old trek solo s frame using a sturmey SRC3 hub rim that I used to use on that bike. Also, how are those caliper brakes holding up?.....one of the reasons I felt locked into converting my pug was the disc brakes on them. My old trek uses calipers too....that SA hub has a drum brake (but wouldn’t use that on a conversion?!) Is the main issue just shifting under speed, or what are the other risks / weak points within the hub? Thanks
I think the most thorough article on IGH and mid drives is this one: www.electricbike.com/mid-drive-kit-igh/ Suppose it depends on your power levels and how smoothly the controller transitions the torque, but he does not recommend using the cyclone 3000w with IGH - I'd imagine same goes for the cyc. Sheldon Brown wrote that the drum and coaster brake IGH's are prone to overheating at high speeds. As for the caliper brakes, they've been fine for my needs (riding cautiously) but I definitely do want a disc brake in the front on my next prototype.
Good video however have been burned by an sram igh. So i fear an igh with that alignment window similar to the sram. They bike shop said those igh had been recalled but mine was so old... Why did you choose nexus over sturmey archer?? I am personally looking to do something other commenters seem to indirectly advise against. I am looking to build a bicycle with an igh using a bike o matic auto shifter for all of the shifting. Looking at some of the comments it might be an idea to install a switch to cut the motor while shifting or another type of pull for a gas motor. On the femce when it comes to gas vs electric since the ebike batteries are based on the same technology as your cell phone.and i think we have all seen how these batteries fail over time. Nothing seems to be reliable enough to really stand the test of time with these motorised bicycle ideas.
lol sturmey is unrefined clunky weak garbage compared to the shimano nexus inter 3 with it far more easy to service, tune/adjust, smooth an handles power well i done nearly 15,000 km with my inter 3 compared to 300km before it exploded on the sturmey.....
I bought the wheel as a complete wheel set and disassembled the rear wheel. I forget what website but I'll try to find a link. The new wheel builder can usually cut the original spokes to the right length.
We'll find out eventually. As far as I understand it - the 3 speed IGHs have a planetary 2nd gear that's part of the axle which makes it significantly stronger than the other two gears and significantly stronger than other IGHs. So far it feels great for me but I mostly stay in 2nd gear, try not to abuse the other two, and don't shift under load. Some people have told me they busted their IGH, others have said theirs held up great with the BBSHD at 52v. I'll be posting updates on this setup every 1,000 miles or so.
yeah I definitely want to eventually, still waiting for the prices to come down... someone needs to design one that can go around the Gates patent and give them some price competition.
@@eBikeaholic need a belt compatible frame to go belt drive, you can retro fit with a kit but standard frames aren't designed to be split and aren't rigid enough...
because they're mostly used in beach cruisers, disc brake versions are also 28 hole (the others are standard 36 hole) 28h isn't an issue tho just use 12g spokes when building a wheel, don't be afraid of wheel building plenty of great videos out the to help with that an spokes can be bought ready to go
I have recently added a Bafang 500w mid drive motor to my recumbent trike Scorpion. While this motor puts out 100nm of torque, and I am using a 65t chainring, I only need to pedal for a few seconds before reaching cruising speed of 30-35 kph in top gear. I am doing 90% of my riding in top gear and my 7 cluster derailleurs are old and complaining noisily. So, it must be time to swap my derailleurs for a CVT hub, but which one to select? Do you think your choice of hub would be compatible? I would like an automatic changer so I can set my cadence and forget the gears.
CVT hub? Enviolo.... Not my preference. My wife's Scorpion FS Clementine uses a Bafang 500W BBS02b with a Nexus 8.... Troublefree for 6000km to now. My Tricon is equiped with a BBS02b 750W and a Rolhoff, recently regeared to have a top speed of 55km/h. The first 300 km were huge fun .
If I wanted to get a 26 inch disc brake wheel with a Nexus 3 on it, did you come across any places offering pre-built versions when you were doing your research?
Yeah I've read that too. I'm under the impression that the 3 speed hubs and the Rohloff are the strongest, but that's what I'm here to test so others don't have to. So far it seems that the most important thing is to not try to change gears while the motor is activated. Feels a bit like pulling the clutch on a motorcycle. I'll publish an update video as soon as it breaks, but crossing my fingers that I won't have to.
@@eBikeaholic From my reading Shimano 3 or 5 speed is the best affordable option but I'd still lay off the power while shifting with any motor. The Rohloff is sweet and will put up with more power but you can buy & replace a Shimano IGH for less.
The Enviolo is awesome but is not cheap and usually found only on Euro-spec e-bikes because they ain't up to running 750 watts or more full time. CVT & high power aren't commonly found together.
well, i hope you're just joking about the derraileur tech being "outdated". internal gear hubs are cool (i also have a commuter with a nexus inter 3) , but derraileurs are still way better in terms of convenience, weight and efficiency. well, you're an ebike guy, so what do you know?
Derailleurs are finicky require precise tuning and more maintenance which most people can't / dont like doing. And people want to shift at a stop which derailleurs can't do. Derailleurs don't last as long w / a mid motor e bike. Chains on derailleur are thinner weaker too than single speed chain used on IGH
I love this video, got an e-boner :) No seriously, I was looking online for something different, on how to change over an internal gear hub that needs to be switched over to a new rim as the old aluminium one is ripped in two. Because I wonder how to spoke a rim yourself and was looking for a tutorial. YT came up with this vid among others and it got me thinking about changing / converting my old e-bike into a new bafang setup, but what are the costs? I have only a low budget and the old bike I have wasn't worth the squeeze for upgrading with a new battery and such. Haven't got the funds for a new ebike also so this vid got me enthusiastic :)
i've done nearly 15,000km with my shimano nexus inter3 with a cyclone 1800w mid drive (i also use sick bike parts free wheel an spiders to run high an low chain rings up front, i locked out a derailleur at the rear for chain tension) , best hub out there in my opinion and i've tried a few, sturmey archer 3 speed destroyed itself in about 300km

CVT hub? Enviolo.... Not my preference. My wife's Scorpion FS Clementine uses a Bafang 500W BBS02b with a Nexus 8.... Troublefree for 6000km to now. My Tricon is equiped with a BBS02b 750W and a Rolhoff, recently regeared to have a top speed of 55km/h. The first 300 km were huge fun .
If I wanted to get a 26 inch disc brake wheel with a Nexus 3 on it, did you come across any places offering pre-built versions when you were doing your research?
Nope, the closest I found was 26" with the coaster brake version on Amazon... I think they were taken off a ride share fail or something.
Most IGH's aren't up to the power of a motor unless your motor is low powered.
Yeah I've read that too. I'm under the impression that the 3 speed hubs and the Rohloff are the strongest, but that's what I'm here to test so others don't have to. So far it seems that the most important thing is to not try to change gears while the motor is activated. Feels a bit like pulling the clutch on a motorcycle.
I'll publish an update video as soon as it breaks, but crossing my fingers that I won't have to.
@@eBikeaholic From my reading Shimano 3 or 5 speed is the best affordable option but I'd still lay off the power while shifting with any motor. The Rohloff is sweet and will put up with more power but you can buy & replace a Shimano IGH for less.
@@michaelsprinzeles4022 What about Enviolo? They seem to be a favorite among the E bike community. They are pretty durable and cheap
The Enviolo is awesome but is not cheap and usually found only on Euro-spec e-bikes because they ain't up to running 750 watts or more full time.
CVT & high power aren't commonly found together.
@@michaelsprinzeles4022 near 15,000 km 1800w shimano inter 3 hasn't missed a beat
why do you need to customize the wheel?
In this case I needed a custom wheel because I couldn't find one with a 24" machined rim and Nexus 3 disc hub. Lots of reasons to go custom though.
Is it possible to do this to a trek fx
mostly depends on the rear dropout spacing and type of dropouts.
well, i hope you're just joking about the derraileur tech being "outdated". internal gear hubs are cool (i also have a commuter with a nexus inter 3) , but derraileurs are still way better in terms of convenience, weight and efficiency. well, you're an ebike guy, so what do you know?
Derailleurs are finicky require precise tuning and more maintenance which most people can't / dont like doing. And people want to shift at a stop which derailleurs can't do. Derailleurs don't last as long w / a mid motor e bike. Chains on derailleur are thinner weaker too than single speed chain used on IGH
with igh as long as you don't shift gears under power you'll be ok.

how many teeth of your crank?
I think the one in this vid was 60T but I've also been experimenting with 56 and 54. 56 seems like the sweet spot for me.
I love this video, got an e-boner :) No seriously, I was looking online for something different, on how to change over an internal gear hub that needs to be switched over to a new rim as the old aluminium one is ripped in two. Because I wonder how to spoke a rim yourself and was looking for a tutorial. YT came up with this vid among others and it got me thinking about changing / converting my old e-bike into a new bafang setup, but what are the costs? I have only a low budget and the old bike I have wasn't worth the squeeze for upgrading with a new battery and such. Haven't got the funds for a new ebike also so this vid got me enthusiastic :)
