Mid Drive Bike Suggestions

30a? Yes please

If we had employees on pedicabs or really loaded cargo bikes we’d find a BBSHD to run cooler. IME supporting several pedicab companies and scores of sales to them. I’m told my last shop is selling 60 dumbed down. 28A 750W. As always YMMV

edit
I think I saw those in one of your pictures but failed to follow up. Hmmmmm... Might be ideal for my 500W.

I have another batch of 100 of the bare alloy 30mm-wide fins on the way now that this new bike is getting built. I don't even consider leaving the motor as-is anymore.

Nice! Perfect! Shared with my friends at California ebike! The new owner has a pedicab biz and several large pedicab operators.

I am getting a TSDZ2 120mm fat bike extension today from Doug at California eBike. I will need to cut threads into the motor housing to attach it. Any idea what the tap is? They play dumb and won't tell me. Is it a plumbing thread? Is there anyone who has done this and knows?

I am getting a TSDZ2 120mm fat bike extension today from Doug Jeannette at California eBike.

New owner and a product not sold whenI was with them. Jeannette is the new owner and is in San Jose.

They play dumb and won't tell me.

I'm guessing it's a new product and she just doesn't know. Doug was a master machinist making those details available. Sorry fella! Did you speak with Jeannette? text me @ five oh seven four five eight two nine four two and I'll text her contact information.

Thanks for the info and the offer. What I will do when it arrives is photograph it and take the BB extension to a couple of farm supply places to have the thread TPI and diameter measured so I can buy the tap. Hopefully is not some obscure thread, but a standard plumbing pipe thread. Thanks again.

All of the ACE hardwares that I know of can give you a hand, and sell you what you need.

A Fastenal store near you?

Fastenal is a short block away. The other side of a parking lot. Funny you ask.

The thread is 4 threads per .25 inch, making it 16Tpi. The outer diameter is 29.8mm. Or 1.17 inches which is very close to 1&3/16

I live i Winona MN home of Fastenal. Should you need anything from them let me know. I’d happily send off to you. High prices but fasteners often unavailable ekes where. Although McMaster is also a great resource.

They are good folks with quality products. If I need to hold up my end I cannot afford Harbor Freight. That would get expensive fast.

We can afford p their prices but not the end ptojecy cost of their failed products. Harbor freight wave just wasted dollars for me. As an aside do you even use an electric driver or ? My arthritis has meant I can’t screw. Viagra fixess the peckerwood but not screwing mechanical problems. Almost true...

I like the idea of Marine Art. I use hand tools, sometimes with extensions for greater torque. I like to feel what I am doing. I can't pet a kitten with rubber gloves. Sometimes I make or modify specialty tools.

Um, you realize that is a HF caliper in your photo?
I have a HF tap and die set, used it many times without a problem, at least no problem other than caused by the user

I got that caliper on Amazon when my old one broke last year. Didn't know it was HF. I have a HF vice. Everyone has at least one vice but mine broke last week.

 

[EMGX]

Amazon lists lots of stuff available at HF, usually at inflated prices but on small stuff that can be made up for by the free amazon shipping depending on how far away a HF is. I used to shop at HF quite a bit and have things like a 12 ton press, impact wrench, couple of work benches, wrenches and sockets, tap and die set even a utility trailer. With exception of a couple of roller seats everything has been of entirely functional quality and have held up to the abuse that I have subjected them to. I wouldn't have most of the stuff that I have purchased at HF if I limited myself to more expensive products because they wouldn't have been worth it to me otherwise.

I will say that AHicks is correct, based on my own experience, for exactly the reasons he stated.

With my mid drive, if I'm not geared down at the start of a big hill, there's a problem. It takes the motor longer than I'm comfortable with figuring out what the heck I've gone and done and adjust to that, so I lose significant momentum. With my hub drive, I knock up the PAS or hit the throttle and the response is instant. Same with starting from a dead stop. I better remember to gear down, or it's a slow start with the mid drive. With the hub, again, kick up the PAS or hit the throttle, and go. I like both my bikes, but the hub drive is definitely "easier" in the sense that I don't need to be thinking and anticipating like I do with my mid drive.

I've said on another occasion that if my hub drive had been available when I first purchased and IF I were confident it would have handled the hills as well as my mid drive does (actually, it probably would!) I would have probably purchased the hub instead.

My response to your observations is IGH. Mine (on an Ariel Rider C class) is a Nexus 7. I still gear down before stopping, out of long habit, but it's nice to know I don't have to, and I sometimes don't. When I do gear down (before stopping), it's because I'm anticipating that the light will turn before I get there, and I want to be ready to power off without stopping. By the way, I rarely use first (granny) gear, and hardly ever use 7th gear. In fact, most of my riding is in gears 2 through 5, pas level one, except when climbing a long, fairly steep hill. Of course I'm old and weak, and I would doubtless appreciate a wider gear range if I were young and buff. The gears I do use seem reasonably well spaced, and I don't recall ever thinking, "wish I had a gear or two between these that I'm using."

I've used derailers for years, and got along fine with them, but since IGH I doubt I'd want to go back. The Nexus uses a twist shifter, which is very quick, and makes it easy to jump over intermediate gears when necessary. Some say IGH less efficient, but I don't know how to recognize that when I'm riding.

(Looking back through the thread, I realize that Ive created a lot of redundancy here. Shouldn't need to say the same thing 2 or 3 times. Sorry)
