I own a Bafang BBS01, installed on my city bike. So far everything works fine. The only problem is that the original (closed) chain guard no longer fits because of the large chain wheel 44T. I'm going to open another topic about this and hopefully someone will have a solution.

'Omafiets type' lol.
The picture of the chain guard you posted is already installed, but the chain is still naked. As you may know it rains a lot in the Netherlands. That is not good for the chain (and chainwheels). It's even worse in winter when it's freezing and salt has been sprinkled on roads in combination with wet snow and mud..

Some people have used flexible plastic irrigation or electrical flex wire harness tubing. I wish I could offer a better answer. Here is a photo of one that I made electric. Regrettably the full chainguard had to go. Does it have an internally geared hub with a single speed chain?

That's a clever solution. Does the diy guard make any sound when cycling?
Shimano Nexus 7 speed. The current status looks like this:

Perfect. It will work. Most likely it makes some sound. It it does not have roughness it should be quiet. I have not done this to a bike. With the cost being under 3 euro it is worth a try. Go to an auto parts store and ask for 'split wire loom tubbing.' Here in California it will rain everyday for two weeks and the 200% snowpack will melt all at once. Maybe I will make one for rain rides. I only use dry lube. Here is one of my daily go to bikes. It is a Nexus 3 with a coaster brake.

Nice bike you have! Is it custom made?
I guess I have to remove the protector first (see picture).
If I don't find another solution, I can still try the diy. I wonder if the result will be nice on my bike. The video of the bike you posted shows the diy guard as nailed it. The guard fits well with the frame, but also the style of the bike.

Thanks, I make custom electric bikes in Northern California in a town called Petaluma. Look for PedalUma eBikes on google maps 56K north of the Golden Gate Bridge, if you want some bike porn photos. It would be nice to paint it to match. If the paint chips just repaint or replace. Here is one I made two weeks ago that is very Dutch with an internal rear brake. It was made in 1996. I fixed it up and painted the chainguard to match the fenders. It has a 750 watt motor and a 48 volt 10.5 ah battery. On most modern bikes I do the wires through frame. Look at the wire management on the white step thru.

I have visited your website. There is a wide variety of bicycles and even a 'omafiets'. How did you get the frame? Import? Did you know we have also a 'opa fiets'? Stands for grandpa bike. I can't find out they are electric bikes. It's clever how you hide the battery and stuff. I assume the 'big water bottle' is the battery?
On my bike, the wires are attached to the outside frame with tie-rips. It doesn't look pretty. How do I feed them through the frame?

OEM chainrings are usually supplied with the correct size plastic guard.
Is this a Bafang 44T steel or an aftermarket chainring?

He is in a rainy urban place and needs 100% coverage to protect the chain, not his pants.
The protective ring that is attached to the chain wheel is made of plastic. The chain wheel itself is 44T.
The bike's original chainwheel is a 38T. Also when I replace the Bafang chainwheel in a 38T I wonder if the original chain guard fits because of a thickening of the engine behind the chainwheel. Maybe if I make adjustments to the chain guard (like cutting into it) it will fit, but that's a risk
In which photo can I see it? What is the diameter of the hole? Doesn't that weaken the frame?

Oh here. I was distracted by an email and hit send. This is advanced stuff and external connections are easier to work on. Most people here have no idea what a Dutch bike is. They just see that it doesn't look or feel sporty and they think of bikes as toys, not transportation. I sometimes find them when they filter down from Canada.

Okay, now I can see the hole.
If I made a hole that small in my frame, I would never be able to get the Bafang's cables through. Just look at the (example) picture below how thick the cables are, let alone the connectors.
In general, Dutch bicycles are made as a means of transport from A to B. For example, work, school, shopping etc. Bicycles are used like a car, but with 2 wheels

38T will lose all offset and change your chain line enough to lose some gears.

@tomjasz, It is a single speed chain to a 7-speed Nexus IGH. I do stuff to bikes that is somewhat like what a magician does. I am not going to just give away all my hard earned tricks. Here are a couple more Bafang builds. The first is an HD, the second an SO2, through frame. Bafang builds are rare for me.
