    The real reason for torque arms

    I was rebuilding my wife's front brakes (V-brake) on her Sun USX delta trike when I happened to check the wheel nuts. Both were really loose. Had she not had 2 torque arms, she could have lost her front wheel. Yes it is a steel fork, but having both torque arms saved her from a serious...

    Troubleshooting Q100's with Ku63/65

    I had an interesting problem and solution that just occured. My trike was riding along happily and suddenly the power dropped way off. I was still able to get up a long steep hill but I had to pedal my guts out to do it. By the time we got home the moter was very difficult to start, but it would...

    New S12S cuts out after 5 seconds

    Why? I tried both an LCD-1 and an LCD-3 and the motor (Cute 100h) that worked fine on a KU63/65 does not keep going. I have the speed sensor set up and it registers on the LCD's. What could be wrong? This controller has never been used before as it is a spare, or was. Oh yeah, the 6mph walking...

    Q100 vs Q100H

    Does anyone know if the Q100h innards can go into a Q100 case? It appears that the cases are the same size, but the gearing is different. The Q100 has 8:1 gears and the Q100H has 12:1 gearing. otherDoc

    OK I am stumped!

    So I have 5 controllers that now don't work. 2 SineWave S12S, one So9P, one infineon (old) and one Ebikekit sensorless. One of the S12S was a known good, but it was removed from the bike and the put back on with the same hall/phase sequence that used to work. No Go. So9P was brand new and ran...

    Another BMSBattery controller failure

    Well my new unused SO9P sensorless controller worked fine for about 4 miles and the quit. Sputtered when I tried to engage it even down hill. Had to pedal and tow back to our house. Luckily this was only about 3 miles. This was bought as a backup controller for my 2 Sinewave S12S controllers and...

    Wrapping Multisport 16000 in a carbon welding blanket

    Does this sound like a sane idea? I ordered 2 18" square carbon welding blankets, one for each battery. I will run a split battery, one on each side of my seat on the trike, just like my A123 packs. The wrappings should retard the heat for a minute or 2 if fire occurs while riding. Otherwise the...

    I'm puzzled about 2x10S parallel packs

    I just bought 2 10S4P packs and I want to run them in parallel. Can I charge them in parallel on a Hyperion 1420 or a Thunder 1220? How do I arrange the balance wires? Thanks in advance. otherDoc

    Schwalbe Big Apples are not great

    Just had our 3rd flat in 2 weeks since changing to Big Apples and Schwalbe tubes. Tubes seem to develop the leaks and show scuff marks on them. one may have been the valve. Back to Walmart tubes and Maxxis tires. I will write to Schwalbe too. Bad news. otherDoc

    How do I destructively remove a freewheel Finished

    My chain kept coming off my highest gear today and aafter fighting with it a few times I took a closer look. The 14 tooth gear (my highest) has practically no teeth left. Somewhere in the house are 2 freewheel removers, but I can't find them. There must be a way to get this off. What is the...

    S12S Sine Wave Controller

    Well my test was very short. I hooked it up with Halls and Phase and checked current flow. It was less than 1 amp but had some hiccups at full throttle. I should have tried several more combinations! Took it out on the road and it ran funny. It was slow and applied the electric brake(regen)...

    Cutouts: Solved! Sine Wave Controller S12S

    Well it worked with the wheel elevated except for a few hiccups at higher speeds. On the road it worked for a few minutes but very low power, then I figured out cruise control and it worked slow but OK for another few minutes. Then it kept putting on it's brakes and then going again (no brake...

    3 wire trigger throttle It's Alive and made in USA!!!

    I just found a 3 wire trigger throttle that looks pretty good. However I faild to consider how to wire it to my 3 wire Infineon controller. It is a Hall throttle. Can anyone help me? I'm guessing that it has a signal wire and a red positive 5v but perhaps different color ground? otherDoc

    Brake light with throttle off

    I need a brake light, but not just any brake light. It needs to work with throttle off, not just with the switch on the brake cable. My wife likes to ride behind me but gets into the flowers and the trees and her brain (which is genius huge) and suddenly crashes into the back of my bike. She...

    Good Things to say about BMSBattery

    I just got my first order from them and it went perfectly. I even had to change my controller order and they sent the correct one! Stuff arrived in about 2 weeks in perfect condition. This stuff is for my Pedelec experiments and the controller is a (Sinewave type with Torque Simulation (whatever...

    I'm considering installing Pedelec in our trikes

    I am considering installing a Pedelec ring and magnet in our trikes but really don't know a lot about it. This would be to comply with local City and State Law. I have seen the Thun setup by Grin tech but want to know if there is a less costly way to go. Consider that I know nothing about...
