Here is a work log of my build.
It's my first ebike. Well, technically it is my second. My first was a 24in BMX. I bought a HS35 from Hyena ( Cheers Hyena and good luck on your recovery bro) and a day after it arrived my 24in was stolen.
With the BMX gone and my dissatisfaction with the weight of the hub motor, i decided to do things properly
I sold the hub motor and AJ took pity on my bikeless ass and donated me this frame -
It is a 26 inch frame that we think had an ICE mounted on the rear. One of AJs mates collected it from the side of the road. Thank for passing it on AJ, i am very happy with this frame.
We chopped 2 inches out of the seat tube down at the bottom bracket and made some custom oversize drop outs for it. Rewelded the chain stays and bottom bracket back on and i gained 2 inches of pedal clearance and 2 inches of wheel base. The cranks were cut 2 inches shorter and will be redrilled and tapped. I needed to move the pedals up 4 inches because i am running 20in 48 spoke BMX wheels with ML75 Pirelli's -
I know a certain past member would be very fond of the frame design and i was going to call the bike the "001" in his honor but i am not the stirring kind, well not today anyway, so instead its "Gus" my daughters nick name.
i have most parts, a few i am still waiting on. Took full advantage of the strong aussie dollar as most everything came from the states.
I want to take a moment to make a few acknowledgements. This is maybe a bit strange in that the bike is not complete yet but so be it. Also please find yourselves in these acknowledgements because they really do extend to the greater ES community as these individuals are part of a whole. I am sure they would agree.
As you will see as the build progresses this bike is basically flat out copying everything Thud has developed with his builds. I am benefiting from what i can only imagine is hundreds of hours of development. I don't know you Thud but i salute you! Thanks for your generosity in sharing your discoveries.
As i mentioned above AJ donated the frame and the cutting, shaping and welding on it is his handy work. It is a honor to work with a pioneer and a generally high quality human being. Cheers brother, there is a shit load of work to go yet!
Matt recumpence for starting this whole shebang! Thank you!
As above Hyena. Even though i wont be using a thing i bought off you (except the CA), you still hooked me up with my first kit and took care of me so i salute you for that!
Justin for the CA. What the fek would i use if i did not have that? It's a treat. Thanks.
And to everyone else for the wealth of information on Lipo's, charging, all the controller info, motor KV's, blah, blah you get the point. Cheers
Also Kaz my wife is mega behind me with this so, thanks Darling.
Righto, i'll straighten my dress now and give the details
I will be running 2 Turnigy 80mm out runners w halls
2 x 3077 12 fet controllers
2p3s 5000mah Lipo at 66v (proberbly upped to 3p3s at some point)
2 x Burties Timing Adapters.
Some temp sensors and cellogs
Forks will use modified mini bike triple tree and cro-mo tubing with clip-ons
The two motors will be coupled with a T10 belt with one way bearings between motors and pulleys.
2 Speed of thuds design with some changes ( i wont have back cut dog teeth unfortunately so it aint the mastery of a Thud box but its got some tricks of its own - update next week)
Scooter hydros on hope floating rotor up front and something a bit different for the rear.
I am doing something kinky for the rear drive, AFAIK its unique so stay tuned. I will have pics up next week of the progress. Its a belt drive with a difference...
I am casting parts this weekend so some of what i am being illusive about will become clear. Some parts i am confident about and others i am not, so well see. The part for the rear drive is what i am not so confident about. I just hope the part contracts as planned
This bike could be a disaster or pay off but either way, along the way, I am definitely open to comments, suggestions and constructive criticism...
