This is so much more like my own bike repairs. There is never enough time, and I often bleed before the end. Thank you for representing, you know, real backyard mechanics this week Craig 😂
Thanks for sharing this struggle! I feel like the tone of a build changes when it’s an emergency repair on a daily bike and it was cool that you felt comfortable enough sharing that journey. I know I get frustrated when I have a mechanical on my daily commuter and get equally stressed out about getting it back on the road.
Having recently acquired an electric assist cargo bike I can empathize with your pain. Heavier bike and load and electric assist means more stress on drivetrain, maintenance becomes more challenging. Many components may not be adequate for the load. Because cargo bikes go beyond recreation and actually fill utilitarian needs I find that the cargo bike has altered my lifestyle and it’s more than a nuisance when it’s broken. Also ironic is that as I watch this video most of the ads are for expensive luxury automobiles that I certainly will never buy. Whatever the problems of the bicycle industry I appreciate being less dependent on the auto industry.
All hail the mechanical bicycle! Looks like a frustrating experience but you did earn a purple heart. I prefer repair vids that show pitfalls, problems and uncooperative parts . We get too many where everything just goes along too perfect. Hard to deal with real life like that.
I had a geared hub fail on me and the three bike shops i took it too wouldn't touch it. I disagree that it's your fault, the system should be able to handle the torque or the motor output should be limited to prevent damage. Great recovery though 👍
This video clears up a few things for me. You have essentially been the guinepig for my next build which will be a diy cargo bike. I was thinking of using an internal gear hub but wasn't sold on the idea, now I'm definately not sold on it😂 I think you could fit a hub motor in the rear with an mtx rim. When high torque is applied through the chain the hub motor will reduce this load on the chain. You could make sure that the hub motor only engaged in lower gears by having a gear cable position switch. This would allow the hub to join in in the lower gears and still use the nice torque sensing system of the bosch when cruising along. One of those cheap 250w geared hubs from ebay are about the same size as that IGH you had on there. The weight gain wouldn't be huge over the stock setup and you could fit a deralieur cassette as you have done. One other benefit of doing this would be that you would have an emergency motor that could get you home should your chain fail. For me this would be essential if I didn't own a car and relied on the bike everyday. Great content, I enjoy watching the builds. Keep up the had work.
That's sounds like a very complicated system for a minor problem. A chain is about £10-£15 so I just carry a spare with me like I would with a spare inner tube. Also having two motors would reduce your range and the hub motor can break spokes, I'd rather replace a chain.
I would rather not have the bother in the first place, all you are adding is a cheap hub motor with a cassette. It's pretty much the same apart from tapping the battery feed for the extra speed controller. I don't think it is complicated to a mechanic. It might be daunting to a DIYer. I have a dual motor setup already. Price of cake once you get over the anxiety hurdles
Eh iv had an internal for for 12 years now 400k a week in Australia and 4200k across Europe, the 105 on my road bike has failed twice and I only ride it Sundays so it’s just luck of the draw.
With this hub it's a no. Seems like it was weak.I see people love Rolhof hubs, going on for decades. First get had some issues, but they sorted that out I read. But a gear hub is heavier. But with a cargo bike you might not bend hanger often anyway. It's more mountain bikers that hit the gnar and crash into things.
Im heavy and my bio- bike too (160kg max,180) and i installed the CUES Linkglide group 1×10 (11-48) it's a little heavy but is made of steel and works super smooth even hill up.❤u channel:)
Bad luck with the hub damage, it looks like a write off if threads stripped. Hub gears are a bit torque limited. Monster leg power😮. Looks like a 1/8" chain and chain ring, so will be interesting to see how the 3/16 chain and alloy chain ring holds up due to the motor torque. Good repair under pressure👍
Well done mate! Cargo bikes are great but they can be a pain! - I have an omnium cargo v2 none electric which also has a derailleur rather than hub gear, would the rear omnium wheel (available from paradise cycles) be the right size?
The Bafang Ultra system I have on my ebike uses a shift sensor to momentarily cut the power during gear changes. Perhaps that Bosch system you have might be able to do something similar?
After about 6 months of online research, I had pretty much settled on the Enviolo with a 750w Bafang Mid-drive...a lot of people said if you take it easy all will be fine...now I dunno...
Get a proper geared hub, whilst the idea behind Enviolo is nice, their CVT design isn't exactly the greatest, prone to wasting energy and failure. CVT's are just better suited towards higher revving engines than an e-bike motor. I'm riding on a SRAM P5 which has been running for some 15-20 years at this point. (and is long out of production).

Okay...I watched your first cargo bike video earlier today. It looked good, but it turned into a cautionary tale.

Well done.
This is why bikes are leisure only for me 🤣 the most I carry in mine is beer in the crate I've called tied in place
The Ergon GP grip series comes with short grips. Really comfy
Thoughts and prayers for the finger, hope you make it. I was yelling at the tele that you forgot the disc.

so much pain and frustration in this video...and way too many zip ties. i hope i dont get nightmares from watching :P
Ebike specific chain and cassette maybe for a future upgrade.

Just looked at the website for that bike and it looks like they are all derailleur equipped now... Coincidence?🤣🤣

"internally geared hub"

You may answer the question later in this video but is the bike still in the warranty period? Seems like something that should be covered!
I have the same concern with my Sturmey Archer hub. There's no one in my area who can maintain the thing.
Sturmey Archer hubs are great! Which one do you have?
@@snakeindigo7085 I don't really know the exact model but it came with my Dahon folding bike. It's got a five-speed gripshifter.
To be fair if you don't smash your knuckles on things when working on the cranks and chainring did you really work on them 😂.
Is that a Halo skewer ?
So nice I´m not the only poor ... .
Tired and Annoyed. That's an old Zep tune, right?
Not everything goes smoothly every time. Maybe you won't do the ''forgot the rotor'' again. but when you are in a rush mistakes happen.
