Re: Tesla Model 3

And 2/3 of the country is not on or near a major highway. Have you ever done a road trip in flyover country or Utah, Wyoming, etc? One or a few supercharger stations on "major highways" may seem to be just fine when there are only a handful of users. If there were 263 million looking to recharge, we...

Re: New "TSDZ2 Torque Sensor Central Motor"

I don't have an IGH, just a standard Shimano 8 speed setup with 68mm BB. My chainline is just about perfect with the TSDZ2 and its stock 42T chainring, maybe only a couple mm shifted to the right. Still have a straight chainline to the 4th gear on the cluster. The motor housing essentially sits wher...

Re: Tesla Model 3

You just expertly made my case that they are great commuter/city cars, but not so much for long distance travel. And, no, electricity lines and infrastructure does NOT run everywhere. This is a huge country. And even where it exists not near enough capacity to service our 263 million vehicle fleet. ...

Re: Tesla Model 3

I totally agree. Tesla makes some nice vehicles but they have a long way to go to catch up to the major manufacturers in being able to build cars efficiently and economically. And Tesla doesn't have any really special proprietary technology that the majors can't at least equal. I don't see Tesla's c...

Re: New "TSDZ2 Torque Sensor Central Motor"

That was actually an option with the TSDZ2 kits my vendor sells. They also offer a 34/42 double ring. I suppose you could install a front derailleur or just manually "shift" the chain by hand for the type of ride you are doing. But so far with my on-road use I am doing OK with just a stock 42T with ...

Re: Tesla Model 3

I don't see how the charging infrastructure can ever be as ubiquitous as gasoline stations, especially here in the USA. Think of a busy Interstate highway with literally thousands and thousands of gas pumps and you still have to wait to access one sometimes. So even if you were to replicate those th...

Thanks, Tom. Where can we find the tutorial? I have recently posted a tutorial that gives instructions for 2. It has links to buy the ‘1 in 4’ cable and plug-compatible throttle and brake levers.

Charger with storage profile?

I have a couple of RC smart chargers for my planes and quadcopters that charge up to 6S and they have profiles to take a Li battery to storage condition by either charging or bleeding off charge to get to the storage voltage. It is good for bringing used batteries up to storage and for bleeding unus...

I've been looking at the open source firmware, read a lot of the install instructions and seen some good videos.

I bet that is a little more involved than the simple blue gear greasing or replacement which from the video you linked seems almost trivial. I'd like to see a video of the torque sensor R&R. I didn't look to see if the author also had one for this procedure. Yes, I'll maybe try to change it as I hav...

Re: New "TSDZ2 Torque Sensor Central Motor"

I wonder if that might be the torque sensor failing? Hi! I've been riding a tsdz2 for a while now, with the open-source firmware. It works quite good, not as good as my former bosch performance but it works. I burned the 48v motor some times ago, I hope because of some water that could get in the mo...

Re: New "TSDZ2 Torque Sensor Central Motor"

First real test ride today on my TSDZ2 bike. I just did 10 miles from the house including the 2 mile climb back up. The bike performed flawlessly and I had a big grin on my face all the way. Used about 1/2 of my EGO 5 Ah battery. I need to get out on my real road bike Monday. After this nasty unride...

The myth of Lance Armstrong is all we have.

Stripped down the small frame Trek and took the frameset to the LBS. He got the BB out OK.

Re: New "TSDZ2 Torque Sensor Central Motor"

I don't think the torque sensor is that sensitive. If the weather ever breaks I'll get out and see how it behaves at a stop with no brakes and report back. As for cadence, the motor doesn't force anything. It has a freehub mech in it and you can pedal at any cadence you want. My 52v version assists ...

The other thing about longer cranks you missed here is that they work better for tall folks and bikes are generally supplied with cranks in proportion to frame size.

I haven't had time yet to dig into your firmware but I figured you would have that in there. Nice work.

Re: New "TSDZ2 Torque Sensor Central Motor"

This is great info and confirms my thoughts. The TSDZ2 is a nice unit but doesn't give the impression that it is heavy duty and built for long term max power usage. It is an e-bike, not an e-motorcycle. I wish the display would show amps in real time. That would make it easier for a rider to keep it...

Re: Understanding and Using EGO Power+ Batteries

Looking at this from the opposite direction, can the EGO charger be used to charge our 52V e-bike battery packs? These packs have only + and - connectors so I assume the BMS is fully self contained and doesn't require talking to the charger. So could one tap the + and - feeds from the charger to cha...

How hard is it to replace this part, and how much does it cost? It looks like we might need to maybe anticipate this and keep a spare on hand.
