I'm back :D
« on: March 27, 2011, 10:07:26 PM »
Hello everyone! I hope winter treated you well. I've been in hibernation on the forum since I haven't even touched my bike until the past few days. Now that it's getting warmer and the snow is disappearing from the streets, I have had a few rides on my bike and it's great to not have to take the bus anymore! I've made one modification to my setup by removing the controller from the black box, which I had mounted on top of the battery by velcro, and sticking it into a bike-bag on the front of my frame. The bag idea I got from Gary, however, the triangle-type he used won't fit on my frame, so I got a slightly different type. The bike looks less bulky and more stealthy now:

Before


After (battery is in winter storage)


So, I never really go past half-throttle on the thing because I'm afraid the 1000W motor will rip out my dropouts. This caused me to look into getting a chain-driven motor such as the Cyclone but, after a week or so of researching, I decided the installation would cause me too much hassle and the Cyclone kits have a lot of negative feedback. My question is, does anyone know if there is a way I could weld on some type of supports to the rear of my frame that would act as torque arms and, in case the actual dropouts break, support the wheel entirely? If there is such a possibility, how do I go about doing it? I don't have any type of welding tools so is it possible to go to some kind of shop to design and install the torque arms/supports?

Also, I don't know if it's just the coldness outside or if I have a bad memory, but I believe the lights on my throttle would usually indicate green all the time throughout my typical rides. However, in my few rides this season, the lights drop to amber and even red at the beginning of my rides as I throttle up. I understand a voltage drop is expected as I add throttle, but I've never had this happen before. My battery voltage stays at 54V after a charge if that information helps.

Here's to hoping spring comes around soon (at least to those of us who still have snow)!

Hi Mike,

Nice to hear from you again! Your bike still looks great! If you recall the 700c bike I let you test drive last summer it is now a dual mini motor drive. I was able to get out today doing some dual mini motor road tests. It was cold but fun! Im uploading the video to you tube now but its late, I'll post it tommorow in my dual mini thread. Check it out. This bike has been reborn and I really love it!

Hi Gary,

Looks like a pretty sweet setup! Like you said in one of your videos, "What ebike?" That's what I love about the hub motors, no one ever knows what they are. People usually guess it's some kind of brake :P

Any idea when the motor creates the greatest moment/torque on the axle? Would it happen at 0 rpm and full throttle, or at max rpm and full throttle while riding (so the motor is resisting all the friction from the wind and ground). I just risked running my motor at full throttle while resisting any movement from the wheel and after a few tries, nothing bad happened :) So I'm wondering if that would be the most torque the dropouts would experience, or if they would experience more while riding at full throttle and full speed.

Can't wait to see the new video of your bike!

Mike

I just noticed you are looking for torque arms for the back. The ones I have are for the front but I managed to get them to fit the rear as well. Every bike is different but they should work on yours.

I don't know it you saw the pictures here are the rear ones again

Hi Gary,

Thanks for the photos. I don't think those will fit on my bike. I bought some torque arms that I thought would fit better from ebay, but even those didn't quite do the trick. I have been riding my bike quite hard lately and there have been no problems, so I'll just stick with what I have for now as I don't think it will fail.

Mike
