new handmade e-bike from Italy

Post by fk100extreme » Jun 03 2014 11:22am

Hi everybody.
My name is Nik and I live in Italy.
Here you can find my new handmade e-mtb.
Ciao

ENGINE
I put a BBS1 350W 18Ah on my new bike. In In the original version it is too weak for an off road bike, so I removed the original software and put a new one without any restrictions, so I can reach also the max power ( 640 watt).
The original software is crazy for the off road use.
On my display I have 9 level : I set a specific power for any level .


BATTERY
36 V 14.5 Ah made with 50 rechargeable cells Li-Ion Samsung INR18650-29E 3.7V 2900 mAh / 3C

FRONT CHAINRING /COGSET
42T CNC chainring. Especially CNC machined to better cope with very steep tracks,
weigh 100 gr. less than than the original 46/48T and gives you higher cadence and better chain line.
Black Anodized Aluminium 7075 (Ergal).
I changed also the last cog of the gocset. I fixed a 42T.

FRAME
Handmade on my garage

Hi, thank you to everybody.
Here you can see my first e-bike . I calls it the “Spider Bike” and it is powered by a 500W Cyclone motor. With 500 watts you can easily use this bike as “an electric chair lift” .This bike does not use derailleurs, but instead uses in IGH (internal geared hub) transmission, the German made Rohloff.
The Spider E-bike has an electronic dashboard mounted on the handlebars and is throttled automatically via the highest quality torque sensor available which is built into the bottom bracket (THUN sensory BB-cartridges X-cell RT)
The bike has a 36 volt, 12-Ah, 432-WH, LiFePO4 Headway battery pack with a BMS. As you can see I took the time to elegantly package his cells and BMS.
I managed to mount both the battery and motor into the triangle. The bike uses freewheel crank arms, so that the bike freewheels like a regular bike when the motor is not engaged:
The controller is up top above the battery. Because the controller is only running 36V at 15A it is fairly small and should be ultra reliable even when climbing.
To finish off the look the battery box is cut in a web pattern.
I decide to make another bike for 2 reasons
1) reduce the noise ( cyclone is very noisy)
2) reduce the weigth . Spider 27 Kg, X-bike 22 kg

are you sure the cyclone is making the noise and it's not due to a crappy controller ?

Hi Lebowski, ......I am not sure if tthe noise depends from the cyclone (gear reduction) or the controller. can you help me about it. can i perform a test to solve this doubt?

I am surprised that to this day, Cyclone/headway hasn't developed a helical-geared reduction, and a sine-wave controller. I remember 5 years ago, there were builders who said that they hate the noise, but they live where the hills are extremely steep, and the cyclone was the only drive that would survive it, since it was a mid drive. (there are many more choices now, of course)

I like the frame very much, it was a very nicely work. my friend you could do a production for the frame and sell them here. if he drop out can be adjusted to 149mm or 150mm , or choose 135mm will be good product people will look for you. hopefully you can ship through out the world . so this frame can accept chromo motor or a cyclone motor, huge or a small one.
Conhis hub motor run on April 2010, 48v 1000watts hub motor distance run 5800km, and Re~alive cyclone kit bought in year 2009, Bought a greentime controller 18fets- 4110 , 48v~ 90v , 3-speed mode. Latest top speed I got for my greentime controller 76.8km/h ! , yet to reach 80km/h, or I will never reached 80km/h ?

superb job, this bike is a pleasure to look at. It seems that you used the same swing arm for both bikes?

Keep up the great inspirational work!

Nice frame, looks light, puts BBS clear of damage, nice low/centre battery weight distribution.

I've ordered a BBS01 350w for a carbon fibre frame 29er MTB I already own. Am concerned mounting a frame battery to only 2 water bottle bolts in carbon fibre might be risky off road?
Can you give more info on software programming? I'd like max power for trails but legal for road. (200/250Pedelec). If it says BBS01 250W on motor I'm sure it won't be a problem on road.

Super nice bike, way to go FK. How do you compare the IGH experience on your first bike to the setup you have now on the newer bike?

Don't think you will be getting any answers. Seems like a year and 6 months since he last time was logged on. And only has 3 posts.
Too bad really, as he did some banging work on both his bikes.
