Re: New "TSDZ2 Torque Sensor Central Motor"

https://sheldonbrown.com/gear-calc.html I know Sheldon's calculator. Very nice thing. Still it can only give a rough idea about what to expect. You need to ride the bike (especially with a motor) to see if the gearing works for your special demand. Especially if you never took much care for cadence...

Re: New "TSDZ2 Torque Sensor Central Motor"

I finished my bike today. Have the Alfine 11 installed, and a 52T front ring, 20T in the back. But this is to high geared. I will revert to the original 42T next and try that. Also have 16T, 18T and 23T for the back to try and get the optimal setup. The IGH hubs almost always have an overdrive func...

Re: New "TSDZ2 Torque Sensor Central Motor"

French legislation now bans the practice of eMTB tuning. If an individual or retailer are caught modifying an ebike to derestrict its maximum speed, the offence is now punishable by up to one-year imprisonment (two year for retailers) and up to a €30,000 fine. https://ebike-mtb.com/en/france-bans-i...

Re: New "TSDZ2 Torque Sensor Central Motor"

I found 34,38, 42, 44 tooth chainrings in AliExpress. However, I can't tell if the 34 & 38 tooth rings have an offset as the 42 tooth ones have. My touring bike has a 42-52 setup with an offset 42 steel inner ring.19-09-06_11.41.43AM-1195x2124.jpg I am asking because I want to make my duel chainrin...

I guess if you don't know how to shift a bicycle you might need a shift interrupt switch.

Re: New "TSDZ2 Torque Sensor Central Motor"

Please input on use of Gear Sensor? What is your opinion on using the Gear Sensor with the TSDZ2?  I have one installed and I find that when I climb hills, and shift, the motor cuts off, and then takes a bit of time to ramp back up again giving me assist. Kind of 'jerky' but I'm under the belief th...

My Trek frame had a welded in plate with a hole since the comfort bikes all had side stands to begin with. I added the extra plate that the TSDZ2 kit came with. The Heim joint allowed me to aim it wherever it needed to go. There wasn't any measuring or planning really. I just bought a Heim joint and...

That Spiderflex saddle looks interesting. I have a saddle with a split nose for circulation issues but the cutouts for the sitbones are the next problem on long rides. Very nice.

I looked at Casainho's speed article. He's running 50x11 top gear and 27.5 off road tires. I'm pretty sure he's gearing for downhill.

The fewer gears in the same space the stronger they tend to be Interesting idea. I've been favoring the 14-speed Rohloff Speedhub, for a never mind speed use case, want max torque at very low wheel rpm Limited to 130 Nm but that's a lot for these IGH right? And the 526% ratio is a decent spread com...

"There are ppl who like pedal bike like bikes over here and there, and same goes for motorcycle like bikes."

Re: New "TSDZ2 Torque Sensor Central Motor"

With the guide on, it's too tight for the TSDZ2 to slide in and fit the way it should. But I can't remove the guide either because I need the rear derailleur. So, what do I do? Replace the wire with full wire guide from the shifter, then route it above the bb-shell. I did the same thing with mine. ...
