Diamant lady electric motor conversion with coaster brake

 Diamant ladies model gets converted with Tongsheng TSDZ2

The model is Beryll Sport which has 8-speed internal hub gear

The motor is 36 volts, 250 watts with retraction, coaster brake (it's a special version, look out when ordering, must be for coaster if you want fot brake..

Bought at https://enerprof.de/

The battery comes from Jose-Power, 36Volt and 12.5 Ah

The conversion is made by T. Starke. Thanks for the pictures, everything looks really nice!

As previously said, it uses Internal Gearing Hub, I think Shimano Nexus/Alfine, which holds up fine normally. And is also used for some Shimano Steps bikes.

The model looks a bit like Diamant Rubin Legere, but it has cassette and so on.. Hmm.

The Diamant Rubin Legere has a big 11-51 cassette in the rear! I guess it would suit a Tongsheng TSDZ2 nice.

Kassett/Klinga/Klingor: 11-51 Tänder

Shimano M5100 Brakes: 

Shimano MT201

Brakes: Hydralic

 Tongsheng TSDZ2 conversion on Giant Toughroad

Check out B. Balcanquall build. Looks nice and sturdy. 

"Looked like this before I started. Then brake lines fitted between motor and BB." - B. Balcanquall

"Here's the prep I did, removed the front derailer and cable stops. Hydraulic lines pushed out of the way, no need to disconnect." - B. Balcanquall 

That's a good thing about hydralic lines, they dont need tensions like a cable wire do. You can just put them aside.

Some bike models can be a bit tricky to convert. Check out this other Giant Escape 2 model which has a diffrent design from the Toughroad.

"Cannondale Trail 7. I removed the cable guide since he didn't need the front derailleur. After some wiggling, I was able to get it on without having to shave anything or take the cover off. I was not able to mount the anti-rotation bracket, but it seems the downtube conduit for the cables kinda creates its own anti-rotation bracket. Hopefully, that will suffice." - T. Okimoto

From Giants homepage about the Toughroad model: "FLY THROUGH CITY STREETS, UP A MOUNTAIN, DOWN A RUGGED DIRT PATH. ALL ON ONE RIDE, ALL ON ONE QUICK AND CAPABLE MACHINE."

This is how the original 2016 Toughroad SLR 1 looks.

Kona Cinder Cone conversion with Tongsheng TSDZ2

More and more people like the TSDZ2..

D. Ridsdill has built this nice Kona Cinder Cone conversion using the TSDZ2 with a torque sensor.

He uses a 48v 17.5 ah Samsung battery.

"I also have a Bafang 1000w mid but this is in my opinion a better system.

Very pleased with it!" - D. Ridsdill

I also have a Bafang motor, a BBS02 but I much more prefer the ride of the Tongsheng motor, especially with the emmebrusa firmware. I hardly ever uses the Bafang motor any more.

"The motor is smoother, gear changes are better. Generally it behaves more like a normal bike. The Bafang is a lot more powerful but more like a moped and a lot heavier."This was my second Tongshen build and now I have been persuaded into building another 3 for family and close friends!" - D. Ridsdill

It has the original VLDC5 display, and uses no throttle.

Nice build of a Kona Cinder Cone! Thanks D. Ridshill for the info and photo!

Lifepo4 cells as E-bike battery

Using LiFePO4 38120 10ah cells in 12s pack

For those of us who don't like to solder batteries these seams like a good alternative when you wanna move away from Li-Ion batteries and go to safer LifePo4 cells.

Photos of nice DIY battery pack: Q. Maxwell

12S means max 43.8V (36V battery)

"I am using Headway LiFePO4 38120 10ah cells in 12s packs. They make a bit bigger heavier pack as energy density is lower than lithium ion but a very stable chemistry. A generic 12s LiFePO4 BMS is performing OK" - Q. Maxwell

If you want 48 volt you have to go to 16S pack.

TSDZ2 conversion on bike with more upright position

 Nice stylized Marin Kentfield (ladies model)

A. Wong installed a new 50t Solid-e-bike chainring. (Bottom one) It is design to reduce the chainline offset by another 5mm comparing to the factory unit.

Nice Marin Kentfield conversion by A. Wong. Also photo by Mr. Wong.

New chainrings, Solid E-bike mounted on bike for better chainline.

Totally replace driveside as far as I can see.

Boardman conversion with Tongsheng TSDZ2

Conversion and photos made by D. Ridsdill

750 watt motor, XH18 Lcd display, 48v 20ah rear rack battery fitted to a Boardman Sport Hybrid.

"Rides nice"

This is a sport hybrid original I believe:

Boardman MX Sport Hybrid Bike - 49cm Frame - 27 Gears and Hydraulic Disc Brakes

Wheel Size: 700C

Straighter chainline and bigger chainring on Tongsheng TSDZ2

Better chainline and bigger chainring on Tongsheng TSDZ2

A. Wong has replaced his selfbuilt chainring to a solid e-bike unit. Here he show the result, which looks really nice!

"1: replaced homemade 48tooth chainring with a 50tooth solid-e-bike unit.  

Result: decrease chainline offset and reduction in friction. 

Note: I mounted the ring on the inner side of the spider to further reduce the overall chainline offset.  I am super excited about the extra smoothness." - A. Wong

"The Solid chainring has a design call "narrow wide" one set of teeth is narrow and one set is wide. this will grip the chain on and keep it from falling off." A. Wong

Selfbuild vs ready bought, 48 teeth vs 50.

The result looks really good!

J. B. Fernandez is using Box Four groupset and a 42t chainring for his TSDZ2. The front chainring has a different design the bigger chainring above.
