Camel
100 mW
Had the bike out on a few good rides! So far all good. Just doing the usual settling in adjustments, setting the front shock.
Had to true the back wheel a bit. Was delivered reasonably tight but needed tightening to really set it straight after a few klicks.
Really enjoying the assist. The handling is sweet.
Took a turn past the office and back on the weekend just to see.
First go at the route I really did some leg assist and really nursed the throttle usage. Was pleased with the battery pack. Got the trip done in around 60mins and that was after going up the lift and chatting to some colleagues for some ten minutes. Route is 20km round trip. Battery was still good for good few more km's.
It normally takes me 40mins to an hour with car in rush hour, just one way!
The route in is a real uphill bitch all the way and the last hill is a real killer. That's where I really cranked the high gear and sucked a good few AH out the pack. The bike would never have made the climb without a lot of Human Power.
Not too perturbed I charged the pack and took the bike out again on Sunday on the same route. This time there was no mercy on the pack. Gave it max boost and held the throttle all the way in the whole distance (Minimal Human power assist).
Result - Surprisingly better. Little Sweat on the run in and the return cruise was a breeze. Until I made it 3 blocks from the house on the return uphill.
Got the controller to cut out - I was expecting this as I had really hammered the assist. Damn - Now I know what it feels like to crank 25kg's of dead weight uphill. When the controller did cut I stopped and checked Motor, Battery Pack and Controller for signs of heat - Surprisingly the motor wasn't even warm, the pack and controller totally cool. At least the BMS works!
I am not too perturbed about giving it horns on the way into the office - The return ride more than makes up for the draw on the battery and I have no issue getting a little legwork in the home run.
My Only concern is that last hill in to the office. I still got to put in a 9 hour day and really don't want the "Gym Bunny" sweat connotation label.
The hub motor is a rear 8FUN 250w unit, the battery pack is a PHYLION 36V 10AH and the controller is a 14 amp unit.
I took the controller out and managed to get the following details off it -
EBIKE SPEED CONTROLLER
Voltage: 36 VDC
CURRENT: 14 +/- 0.5A
Low Voltage: 30+/- 0.5V
SPEED: 1 - 4.2V
TYPE: SY-WK2Q36-250
Also a batch no. yadayadayada and Serial no. yadayadayada
My question basically is this -
Seems like I need a little more TORQUE (The speed doesn't phase me a bit - Wellllll - Not at this stage anyway)
Could I not dump in a a higher AMP controller? Realistically a MAX of about 25 AMPS (Just for those hills) Sure I'm gonna reduce my assist distance but we know this is a give and take scenario.
Would the 8FUN be able to handle a couple more AMPS without crisping the winding's?
I really want to make this work for a while.
I know this is a very entry level setup, but I have firm sights on a decent upgrade. Just got to save a few pennies for my wishlist -
Must get CA (Cycle analyst)
Must go to higher voltage - 48/72
Must get real nasty AMP chewer motor
Must get a set of LUMINATORS
Must build BMS balancer
Must buy/build MEGA V/AH Battery pack
etc, etc - Damn, no wonder this is endless-sphere!
Cheers - Gonna brave the cold tomorrow and take the bike (Probably give me an extra 10mins at the coffee machine - )
PS: Attached elevation graph (Courtesy of http://www.mappedometer.com/) of the round trip route. Grind in - All pleasure on the return.
