Then on Thursday, August 20th...... I DID IT!! I TOOK THE DT-CYCLONE OUT FOR HER VERY FIRST POWER RUN!!!! WOOOOHOOOOO!!
Ok, lets start with the final build. Lined up the motor mounts and secured them. I drilled and tapped holes for theh front grubs screws for the big motor mount. Couldn't get into doing drilling and tapping holes into the other side as the small triangle was too small. The front grubs will do to prevent the motor from torquing and twisting. ( I hope)
Then adding a small shim to the bottom bracket to set the chainwheels out a wee bit more for a better chain alignment. Installed my heavy duty KMC chain (and it looks monsterous) and hooked up the tension wheel.
Setup my Ping battery with some Anderson Powerpoles (THANKS GLV FOR THE HELP!!) and was pleasantly surprised that when plugging in the power I did not hear any arcing. I was all 'fraid of hearing the electric "crack" noise. Neat-O!! I tied down the battery to my Axiom Rear Seatpost rack. Nice and secure it won't go nowhere.
Got my Battery all charged up, balanced and ready to rip, thanks to Ping for his tireless efforts to respond to each and every question I had about the first charging of my battery. THANKS PING!!!
The controller? Another strap secures it to the frame by the seatpost. Git 'er done!
Ok, so this afternoon was the moment. This is to be the big show, the fruits of my labour of putting it all together. I was all nervous and ran around the condo back and forth getting stuff I had missed for the first ride.
Finally got to ground level out into the wonderful summer day. There was a nice warm breeze and the sun was full out. A beautiful day for my first electric bike ride.
28-44T combo I topped out at around 42 km/h. The torque is 'fierce' !! I started off slowly then throttled up. But I can feel the instant response and the whining of the motor and chatter of the chain drive was totally awesome. I zipped thru the neighborhoods residential streets away from traffic for a bit. I was grinning from ear to ear. Eyes were watering from pure joy and wind from speeds of 40km and up.
Turned out my front brake wasn't really setup properly but only found out after I finished the ride. :shock: Its solid now. 8)
So I rode around the area for about 45 minutes, doing some WOT here and there to hit my highest of 48.9 km/h I only upshifted two gears .
Man, it was Nukkin' Futz!!! The best ride I had on this DT folder. Can't wait till I get another chance to ride.
So there's my Downtube Ebike build. There will be additional refinements later, such as putting my battery in a nice protective case and managing all the wires neatly. I'll update with pics as they come along.
Thanks again to all the great folks that have helped me along the way. Special thanks to Kentlim that influence me and guided me with my build. Most appreciated Brother!
