Trek Navigator 400 IGH TSDZ2 project.

I went shopping for parts. I ordered a couple 44t steel cruiser chainrings for 1/8" chain. They have an offset built into them near the outer edge....

I saw this double chainring setup fpr these. It doesn't help with my chainline ASFAIK. But an interesting option. 52T/42T

I got the bike back from the shop. The 73mm BB shell was cut back on the drive side until the motor touches the frame. This gets me to square one relative...

For my current project, which is a guest bike for flat terrain, I'll try the existing Nexus 7 IGH. My own bike has an 8 speed 50t x11-40t Shimano Rapid...

Very nice. There was a cargo bike IGH question at Endless Sphere. That looks like the answer....

Do you mean SA made an IGH/casette hub? What model is it? It sound wonderful.

I want to replace the narrow Trek rims this came with and install some bigger tires. I could just do the Schwalbe Big Apple Plus. But pedal overlap is...

OMG. If that thing gets magnetized he'll have a giant gyroscopic compass needle. He'll only be able to ride due magnetic north. Any nails he picks up...

I never liked the external click box, but the rotary Shimano IGH shifter screws up the chainline. Luna lists new DDS hubs in their catalog. I'm a Retro...

You need to look into how it stops also. An 8# flywheel at 28" diameter is no joke.

[Retrorockit]

Don't forget SRAM IGH....

[Retrorockit]

Maybe a lower gear ratio is in order? or is it a hub drive? I forget. I doubt you want to be going 66MPH on this setup. Now you need to make some ballistic...

I've started another bike project. 2003 Trek Navigator 400 14.5" frame comfort bike. Nexus 7 speed IGH hub. 36h rims. 185mm BB7 front disc brake...

I could build that! My local E bike shop has a 3D printer. I'll see if he has anything. I'm actually shocked that it fits at all....

[Retrorockit]

I thought TS stood for Torque Sensing, but actaully it's Tong Sheng. Not Bafang. Studied up on it. nice features, not as quiet or sturdy as the Bafangs,...

I just got my TS 750W motor and Shark battery I was surprised the the shark battery actually fit inside the front triangle of the tiny Trek Navigator...

[Retrorockit]

My BBSHD says 750W. I suppose it would be with a 24V. battery.

[Retrorockit]

I got my parts in today. The Shark battery actually fit inside the front triangle, but no rom to take it in and out of the braket. I saw some side pull...

Somewhere in this 175 page thread they mention a supplier for that.

In my state it's illegal to ride an E bike under 16 years of age. The cops could stop him just to check on that in Florida. Good judgemnet can be an issue...
