Hadi Teherani - rebuilt..

I have an old Hadi Teherani eBike that i'm going to upgrade.

Original motor is a ??w 36V brushed direct drive motor, but the controller is (as I can see) limited to 180W - so not quite powerfull..

I'm replacing the motor with a generic'ish 36V 250W hub motor, the controller will be a KT 15A controller (right now I'm using one without hall sensors, and not a Sine controller). Battery will be a custom made 21700 48V pack made in a 3d printed "Duracell" battery. I'm trying to build is a stealth as ever possible - but since it is an old frame not many options to route the cables inside the tubes :/

:lol:

Love it!

I've had an idea for some time of making a bigger then usual water bottle (2L [0.5G]) and stuffing as many Wh in it as I can.

You dont want a frame with holes in it for cable routing as those holes are a weak point and thats more so if your hanging a battery off the top tube, or your a heavy rider.

I like the Duracell battery case. Did you print it yourself or are they available to purchase somewhere?

Is that copex as chain guard or an available product not seen that before ? :thumb:

The model is available on thingiverse - however I made a ned bottom cap with an XT60 in it. Currently designing a “bottle holder” also with an XT60 - so I can just remove the “Duracell” battery from the bike. The model needs some scaling though - I’m trying to fit a 13s3 made of 21700 cells and a BMS inside it.

I have no idea of what it is called - it’s just a flexible plastic “hose” - but I do not recommend it, it collects water like a sponge..

Hi! I bought this bike couple months ago in Berlin and now my bike's motor controller is stolen.
This controller has an unusual 12-pin plug. I couldn't find the exact type of the controller.

Dear PeterpDahl, could you suggest:

• will I be able to rewire a generic motor controller like this - https://www.amazon.de ... /Brushless-Controller-Aluminium-Electric-Bicycle - and use it instead the original one
• I read somewhere that the original motorwheel has a brushed motor inside. Should I search for a controller that was specifically built for brushed motors?
• or is there a chance to find the exact type of the controller for my bike?

The OP mentioned it's a brushed motor in the first post. If it's a brushed motor, you need a brushed motor controller.
