Re: Framed Minnesota LTD Build

How do you keep it from automatically turning off while riding in unassisted mode. Nobody seems to be concerned with it. Don't know any other way around it but to periodically turn on the assist after every 5 minutes or so, otherwise I have to stop and dismount if I don't want to compromise the tor...

Re: Framed Minnesota LTD Build

This is my stealth e-bike build. TSDZ2 52v with a 6ah mighty mini battery in the tail bag, 100mm fat bike adapter, VLCD-6 display and a 30t chain ring for hill climbing. The Framed Minnesota LTD was a great platform for the build. Decent specs for just under $1000 and the chain line worked well wit...

Re: New "TSDZ2 Torque Sensor Central Motor"

What is, in your experience of fried motors and temperature readings, the safe Amperage we can set for the TSDZ2 in order to keep the temperature under acceptable limits? I've actually set 16A (with 36v means about 500w) and does not seem the motor heats up much. I use low gears when climbing, such...

Re: New "TSDZ2 Torque Sensor Central Motor"

the only thing is that the thermometer is broken, but it correctly reads the room temperature and also the body temperature. During the test I touched the body of the engine and I could hardly hold my hand, I think over 55 °, inside obviously the temperature is much higher. Unfortunately, in my hil...

Re: New "TSDZ2 Torque Sensor Central Motor"

Yours is very high geared. Is it just a single speed rear or is 28t your biggest cog on rear cassette? I swapped my 42t chain ring to a 38t narrow wide and my biggest cog on back is 36t I can ride up the same hill with power off but it flys up with it on. Im on 26inch wheels as well so mine is a lo...

Re: New "TSDZ2 Torque Sensor Central Motor"

Just had my first powered ride.. im more than impressed with how it pulls up hills. Only had time for a quick play. Battery started out at 53.8 volts. I used a 5 ohm vape wire to knock it down bit by bit. At 45.5v the walk mode worked intermittently for a little bit but battery recovered to 46.5 vo...

Re: New "TSDZ2 Torque Sensor Central Motor"

Throttle: Throttle is available for both, but it’s unnecessary with the TSDZ2. I didn’t use my throttle either with the BBS02. I preferred to engage the pedals. I found it uncomfortable using the throttle exclusively, since you are putting 100% of your weight on your seat. That is why ebikes need s...

Re: New "TSDZ2 Torque Sensor Central Motor"

Please take some pics to document the maintenance. Perhaps the mods could make a TSDZ2 maintenance sticky for users to refer to. After riding in a misty weather during autumn and not using it for two months the motor now seems a bit louder and grittier. Probably will have to check the grease level ...

Re: New "TSDZ2 Torque Sensor Central Motor"

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 motor (the cover was not totally waterproof because a ...

After riding in a misty weather during autumn and not using it for two months the motor now seems a bit louder and grittier. Probably will have to check the grease level on a secondary gear before finding out if white lithium grease is suitable.

Re: New "TSDZ2 Torque Sensor Central Motor"

Have the same type of noise in walk assist mode as well. On top of that it seems like it has suddenly developed some sort of a gear meshing noise when spinning the cranks with the motor completely turned of. Probably due to riding in a 14t sprocket for two hours on the flat with 90 rpm cadence and ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I got my motor today (48V). I plan on using the open source firmware, but I wanted to bench test it with the stock firmware first to make sure it works before I void the warranty. I couldn't figure out a safe way to put enough torque on the cranks with it benched to get the motor to turn, so I trie...

Re: New "TSDZ2 Torque Sensor Central Motor"

It actually does feel like a motor is working against the rider or rider against the motor, so it seems like it goes slower than it would normally do. That might be the reason for being so exhausted afterwards. Takes the edge of the hills a bit while in turbo mode and first gear though, on the other...

Re: New "TSDZ2 Torque Sensor Central Motor"

Are there any blue nylon replacement gears with sufficient gear mesh engagement available? Heard in another thread this issue has not been approved/addressed by adequate amount of peer review so it's a bit too early to worry about. Or it requires complete redesign of the whole unit?

Re: New "TSDZ2 Torque Sensor Central Motor"

erian, Why would you put an electric assist on a racing bike? A TDSZ2 system with a large battery could nearly double the weight. The bike would NEVER have racing bike characteristics again. In my view a hybrid type bike, with suspension, would be a better choice. The assist will compensate for the...
