Re: New Build crystalyte 4080 / 3580 down hill bike UK

personally I would NOT put the batteries on the front forks ! :shock: :shock:
because any weight you put on the forks will make steering heavy and slow in reaction .
unless you drive on paved roads and mainly straight .

Re: gearbox bike, belt drive, sequential shift etc.....

very smart idea , there is also Pinion that makes nice gearbox , and Suntour . I think it is similar , as concept , to the Honda bike presented some years ago RN01 . will it withstand the torque that an electric motor has ? I recently spoke with the engineer that designed the Pinion gearbox , and hi...

Re: Modifying a Hammerschmidt for mid-engine (freewheel?)

I think the idea is very good .
the system is working like a normal sungear .
parts are custom made , don't think they are easy to find off the self .

Re: Ebike "The Resurrection"

I'm doing something similar , but don't have any pic at the moment. one thing that is not clear is about the balancing wires : here we have 10 battery packs , but only 5 exit for balancing ? how can this be ? when you want to recharge all packs , you must break up the wiring and ri fix them later . ...

Re: which used DH-frame for mid-drive build?

I would go for the Kona Kahuna , and change the forks .
in the frame you should have enough space for some good batteries , 15 ah.,and the controller .
but ..... if you really want to make a nice job , cut the frame and add the battery container ecc , Scott Nitrous .

Re: C rating Batteries

as said most of things are already set . I must take a decision on what kind of batteries to run. the RC lipo are relative cheap , and offer the best ratio of power to Kg and volume. the A123 , and Kokam are nice but , we have some big disadvantage : power / volume per Kg of battery is lower then RC...

Re: New serious Offroad bike : The Chainer

what about the Cr/mo tubes I highlighted to you .
were they open to sell some to you ?
or maybe you are using this as a prototype frame ?

I will start mine at the end of August after visiting the bike show in Germany .

Re: New serious Offroad bike : The Chainer

very nice job mate :wink:
the SS 316 is a very nice steel, if you weld it with the right wire , welding is a piece of cake .
also the final result will be nice smooth and elegant .
may I ask what kind of angle did you decide on the front ?

all old bike were braised , because at that time TIG welding was costy and not so commune . If you brase the joints I would not go over 1 mm thickness for joints . pls consider that the final thickness will be the joint and the wall thickness , in CoMo steel , so aprox 2,2 mm !!! that is enough for ...

Re: enduro E-Bike ,need HELP !

Hi Incememed nice video you have posted . that's more or less the idea . In my area we have more hills and mountain tracks . so the goal will be even more difficult. after going through almost all treads on this and other forums ,over 2 mounths of reading I have made up my mind on the motor. :shock:...
