    Going Brushless. Two packages, help me pick.

    So I currently have a Motenergy ME0907 Brushed motor and Alltrax 450A controller. The battery is an 11 Module Leaf 58Ah pack. 90V fully charged.

    The ME0907 brushed motor failed in a great display of Plasma arching while riding through a busy intersection.

    This is the 3rd brushed motor i've Nuked in 8 years... I'm over it, want to go Brushless. (Note, not all were Motenergy motors, and different bikes)

    So here's where I sit...

    Option 1: Motenergy 4201 Motor, Kelly KLS7240D. SLIGHTLY less power, but brush-less at 14lbs less then current setup. At just $1,000.

    Option 2: MOtenergy 1115 motor, Curtis 1236SE-6521. Great power, great reliability, and similat weight to current setup. But a whopping $2,400.

    Option 3: Slam in a Motenergy 1003 dual-brush motor and deal with DC power... $650 (Don't really want to do this, but cost is tempting)

    Is anyone on here running these setups? DO you like it? Hate it? I've heard sketchy things about Kelly Controllers... Have people blown up the Brushless Kelly Controllers?

    THanks for the input.

    Kelly specs are pretty optimistic in my experience, so maybe do some research to see what others say lately about that combo.

    The me1115 (or even me1114 motor) is good, air cooled. They're the same Stator and Rotor as the ME1302/1304 respectively. I've got Sevcon files for the 1304, and we could likely modify my Size 4 file for the 1302 to fit the size 6. Might be able to find you a used Size 4 that would fit easier as well.

    Hey Just curious, Did you destroy the ME1003 16-brush motor? I have that exact Alltrax controller, and one option was to upgrade to the ME1006.

    I have and am still running a ME 1003 in the Cafe Bike. I did burn up a brush pack once... doing 120MPH. (with a 1000 amp controller at the time)
    Swapped the brush pack out and it is still running fine today. (not racing it now)

    Never a issue for street use. (running 100V through a Kelly 600 amp and according to my CA it is pushing out 400+ amps)

    You need to get the brushes seated, but after that...have fun!!

    I am having a blast with our new brush less setup (Travis) on the drag bike ($$$) but if money is an issue, a ME1003 is not a bad way to go.
