Bafang BBS01

That chopper bike would stand out in Amsterdam. It is called a SIKK. It is a large bike. The owner is 120kg. It has a 750 watt 120 nm motor with a thumb throttle on the left. Okay here it another bike that is thru frame with a torque sensor and throttle on the left. I had to drill. You would also never see it in the Netherlands. It is also 750 watts. This one is called a FatBoy from Specialized. Oh, that lube is MucOff C3 ceramic dry lube.

I was not aware that the bike is so big. I thought it was a bicycle for young people.

We call the bicycle that stands against the pole a mountain bike. Only they don't have such extremely thick wheels. There was a time when mountain bikes were seen quite a lot on the streets in the Netherlands. It was kind of a trend. Nowadays I hardly see them anymore.

Nice environment by the way! California is great.

In the tropics and by the sea and with an exposed chain with a derailleur, you need oil. Mobile 1 is ideal. I use that when I soak the guts of an Alfine or Nexus. Do you want me to stray off topic to show, 'Bad Dog'? I regularly use modified PVC tool extenders, but this one is special and uses a IGH cog.

So first soak the Nexus in Mobile 1 and then put Super White on it? What about the inside of the Nexus hub?

I once took such a Nexus hub apart with the idea of also greasing the inside. A spring popped out with parts underneath. I was never able to put it back together after that and had to buy a new wheel.

I believe it's 8 wires... Shouldn't be too tedious.
Try to stager each wire so you can still insulate and have a thin bundle

Thanks for the tip. I'm still unsure whether I'll leave the wiring as it is for the time being or whether I'm going to adjust it to the inside of the frame. For now I need the bike for work and other things. Unfortunately I don't have another bike. If I'm going to do it, it should be during vacation time.

First put a large heat shrink tube to one side away from the action. Each wire gets soldered and the union covered with small heat shrink. Four go one way and four the other. Then slide the larger tube over them and shrink it.

Thanks.

Hopefully the shrink tubing will not cause a bulge when the cable is fed through the frame.

Here is what Bad Dog looks like. It is off topic, forgive me. I just made it from a tool extender. I hate being bitten by loose dogs when ridding. How about you? It takes 1 second to activate and deploy.

What's that for?

Regardless the chainline will move out 15-20mm. Sorry this old brain can’t remember the exact measurement. That said, why 38T? Lots of inclines? In my limited experience 42T is a BBSxx sweet spot.

BTW, nice looking bike from what I can see. Something ready to roll eBike buyers miss. Kitting an upscale bike can be a superior build. And a build best suited to individual tastes and geometries that are harder to find as finished bikes.

good on you, builds IMO are far more sustainable.

being a plant science guy, Johnny come lately to anything electronic the best investment i made was in a superior soldering iron. And good Kester soldering products. My TS100 (link) made soldering a pleasure rather than an adventure. YouTube school for the terminally inane did it for me.

38T is because of the original chainguard that don't fit anymore. I thought that if I replace the 44T in 38T the chain guard will fit. Theoretically...

Seems like a handy wireless soldering iron, but is quite pricey in my opinion. Mine still works on electricity and because I don't solder that often, the wireless one seems superfluous to me.

Last one first. The original guard won't work, just let it go. I use that shaped PVC pipe with the grip to extend the leverage of some tools. Last night I put a Nexus cog on it. California is nice but we have many homeless people who really should be institutionalized for mental health and substance abuse issues. Many of them have large off leash attack dogs that will jump and bite. So I can swing that to let them chew on the cog instead of my leg.
There is nothing wrong with your build. I am just weird and do things differently than most people.
What I do is extract the core of the hub and soak that, then apply lithium grease to the gears. Shimano sells expensive oil for this.

Now I understand you. It's self defense.

Just off-topic: I sometimes watch Peter Santenello, a vlogger on Youtube who vlogs about all kinds of social topics. Coincidentally, he had a vlog about Venice Beach where there were also problems with the homeless and drug addicts. It's sad to see people suffer like that.

I've already watched that YouTube video, but according to some comments, he's not doing it right: "Really bad idea to put a dirty, rusty hub gear in clean oil, especially the end of the external sprocket first. Strip it, clean it, grease it up, put it back together. Yes, for a while it will feel better because it has some oil ... but you're creating a grinding paste of dirty, rust & oil that will harm the gears."

I clean it first. I also agitate it in the oil.

@PedalUma

What would be the diameter of the electrical flex wire harness tube you mentioned in the previous posts (Youtube video). I think I'll try that.

I have never done it but think about 12mm would be about right, or just under 15.

I already knew the Chainglider. I'm just afraid it will make noise when I'm cycling. I also read that the bicycle chain corrodes the plastic of the Chainglider.

I've been running a BBS01 and 42t Luna front chainring on my bike, and the chainglider works for me. My bike is a work in progress and has changed over time as I've added Dutch components including an Azor drum brake fork and taller adjustable Ergomatic stem. Here are a couple of pictures showing my bike with the Nexus-8, then with the Enviolo. In my experience there is only a slight occasional rubbing noise that goes away if I adjust the rear piece a notch. When I had my shop swap out the Nexus-8 IGH for an Enviolo CVT I just needed to buy the different rear chainglider part and kept the front part, so 5 years and no plastic corrosion. The chainglider keeps my chain very clean in winter riding.

@Dewey

Thanks for sharing your experience.

So it doesn't make as much noise as some say? I still don't really know what I want to do. There are 3 more options and I have to think about it.

I had almost the same stem in my Gazelle.

Not that I notice while riding except only occasionally, and IMO it doesn't do either the chainglider or chain any harm.

I had almost the same stem in my Gazelle.

Yes, I had wanted a Gazelle Switch stem but my bike has a 1 1/8" steerer tube, and the Batavus Ergomatic version fits that size rather than for a 1" steerer as used on the Gazelle stem.

I even fit a Widek crown steel bell... I admit I want a Gazelle ebike!

This one is all Dutch but it was designed in California. It is called a Breeser. By Joe Breese. It even has the lock and dynamo.

Nice job of the conversion @PedalUma really clean.

Chainrings under 42T can mess up a BBSxx chain line. One exception, the $150-$180 Lekkie 40T kit.
