    new cyclone 3000 w mid-drive kit?

    Hi guys, I'm installing the cyclone kit but I want to use my Magura throttle. I don't have the connector which comes with the stock throttle (key+voltage indicator). Where am I suppose to connect this wire ? On the other side it seems to go to the hall positive. Thanks, Paul

    Yes, chain on the first reduction. It was 54/11, I changed it for 68/11 with #25 chain. My reduction to the crank is 24.7:1

    Wow awesome post man ! I have a gng kit on a Kona stinky at 3000W, it pulls strong :D The swing arm bends a bit when going in the small gears. Do you feel the same on your frames ? Where are you from ? How is the Santacruz v10 to ride ? :D 8)

    is this good news? (Graphene battery)

    I'm wondering if the rating of the 6S 12Ah at 15C is accurate. That would be enough for most of us to use in 1p configuration. I can't wait to see batteries with high discharge capability, high density 250-300Wh/kg and affordable price. Maybe in 5-6 years :?:

    is this good news? (Graphene battery)

    From a comment under the video of createthis: "Calling these LiPo's 'graphene batteries' is a complete misnomer. They are Lithium Polymer batteries with the graphene used to pass conducted electricity from the cells. We're still a long way from GRAPHENE batteries."

    Thanks a lot teklektik. I disconnected the RTN wire which was connected to B-. I tried to run the controller this week-end but there are two led codes errors: 1-3 followed by 2-4. 1-3: Low voltage error 1. The controller will clear after 5 seconds if battery volts returns to normal...

    Hi, I wired up my new kelly controller KBS72181E but I want to check two things before connecting my battery: The wiring diagram is here http://kellycontroller.com/mot/downloads/KellyKBS-EUserManual.pdf p12, I connected RTN to B- battery, is it ok ? Because in the manual they say (on the left...

    LightningRods mid drive kit

    For which reasons did you decide to change the motor ? Is it lighter/cheaper/ more convenient ? What is the price of your kit (small block) without the Cranckset+ BB (68mm in my frame)? I want to build a 3kW mid-drive and use 3-4 gears (to keep the chain a minimum straight)

    BBS02 Chainring 52T cheapest one ?

    Obviously, you don't know the difference between power needed and efficiency. You must be novice. The red curve on the simulator represents the power of the setup (output power, power at the wheel). The black curve is the load depending upon speed. Hence, the speed of the setup will be at the...

    BBS02 Chainring 52T cheapest one ?

    No, maximum speed (full rpm) is only reach when you have no load. It never happens except in a very particular case: when you have enough speed in downhill to balance the full rpm of the motor with your speed. Above that speed, the motor is regenerating energy (or freewheeling in your case)...

    BBS02 Chainring 52T cheapest one ?

    @Alexis: It's again false. 1) the simulator is made with real number (test-bench) and then it's extrapolate but really close to the reality for "small power". 2) Can you read ? 3) You forgot the load of the bike at speed. Therefore, you're not running it at full rpm as you think :roll: ...

    BBS02 Chainring 52T cheapest one ?

    Deja, evite de prendre un ton condescendant, tu n'as pas la science infuse. :shock: Deuxiemement, les questions de rhetoriques sont mal venues, on est sur un forum international et par ecrit donc le ton de la voix ne peut pas passer par message. No, just do some research on electric motor...

    HPC Revolution XXX

    Nice looking frame 8) 8) Unless you don't plan on using bicycle drive train (which doesn't look like where you're going), a RV160 is way overkill for a bicycle drive train. A RV120 pro peaks at 15kW (according to constructor, so maybe 18-20kW in real situation), enough to throw you on Mars...

    BBS02 Chainring 52T cheapest one ?

    You are comparing ICE engine with electric motors, it's completely different :lol: Power = torque * speed If you have a bigger chainring, the speed of the chain (or of the chainring) will be slower to achieve the same speed. So as we are talking about same speed, it means also same power and...

    pchen92's Kona Stinky GNG build

    Of course I don't need such a big bike. But I used to have a XC bike (full suspended) with a BPM and I didn't like the comfort (not enough travel suspension). A lighter bike would be only 2kg lighter, maybe more expensive and less bullet-proof ? 2kg won't make a huge difference since I will...

    pchen92's Kona Stinky GNG build

    Hi all, After numerous hub builds and a DH Team + Cromotor that I still run, I wanted to build a lighter ebike with lots of torque. I picked up a Kona Stinky a few months ago and had fun with it jumping off curbs, wheeling, ... (I live in Paris, so offroad will be quite rare :roll: ) I...

    GNG, 1000W 48V BB-drive, $400

    Hi, Does anyone know if a 12 fets Infineon sensorless controller will work at 18s with the gng motor (4500rpm) ? The motor is 8 poles I believe, so around 36k erpm Thanks

    First build - Vector (e-kross) frame

    Hi, what is the wheelbase of this frame ? To compare, the Giant DH Team is around 110-115cm. I'd like to get 5cm more. I plan on getting the vector frame and Max-e once I'll move to Munich for the summer. Greetings from Paris :D 8)
