For a 60 km trip will it draw more power from the battery vs. Stock even though I'll be pedaling the same amount in slower sections of my trip. I have about 5 sections that are really fast I.e. bursts of speed for 10 km and then 2 km stretches.Rix said:proper159 said:Getting pumped to make the conversion to MC rear tire from Morati. Trying to visualize the difference in speed/handling vs. stock motor (The finished MC wheel has the 4504 or whatever the one Rix has). I'd gladly take higher torque but I've grown accustomed to the "freight train" feeling once I shift to 9th gear. Rix, I know that you have done some swapping with the stock to the 4504, I'll PM you to get the details on how to find the perfect balance between speed and torque.
I haven't tried the new motor, but how would a concrete hill that is about 400 to 500 metres and medium to high grade steepness with about 400 m flat lead up feel like? Right now, I get into the attack position at the stop light with my gearing at 8th gear. By 150 to 200 m on the flat, I shift into 9th gear and pedal like a mad man with full throttle. I have to keep pedaling and keep the throttle on max or else I lose all ability to regain torque and speed midway up the hill. I have over 40 cars chasing me down usually but I can match their speed. Will the 4504 drop down to 45 km/hr at around 200 m on the flat? If it does, can I use that time to lay off the throttle and shift up to 9th and then pedal like a mad men with full torque? Will I lose torque somewhere in the middle of the hill?
Yah Proper, its a 5404, and you should pull the hill a little faster than you could with the 5403. The 5404 should give you a top speed of 45-46MPH or about 70-72Km/H. Its a good motor, my dad has it on his Bomber, and would ride anything else.
You should be getting north of 80 Km/hr. With same volts and amps input, the difference between the 5404 and 5403 with the Bombers stock pack is about 6 mph or about 9-10Km/h, that was my findings. So if you are getting 77km/h, figure on 67-68 km/h. Bone stock wheel setting should be around 2040mm, I have seen default settings from 2038mm to 2055mm for the 24x3 Duro Razorback. You could be off by as much as 40mm and there would only be a 1-2km/hr fluctuation with your velocity readings, not huge. How I figure out the mm input is measure the wheel inflated in mm, take that number, multiply by 3.141 (pie) and the number you get is the what you should program for wheel size in your CA or DC1. This does not work at all for MAC geared hub motors and the CA. Provided your pole count is correct, (12 for the 54XX motors, 23 for the H40 and TCXX) it will be really close to actual speed.
