    Don't buy lekkie buzz bars. Manufacturing fault.

    I agree with tomjasz, I have had very good luck and service with Lekkie components, especially their chain rings :).

    Don't buy lekkie buzz bars. Manufacturing fault.

    Haystacks...Thank You for the info! What about heating the axle with a propane torch to get the loctite to let go and then using a sharp chisel or punch to tap the outer edge of the bolt to get it to turn? Propane torch is well above the 500F removal temp for loctite. I'd wrap the axle with...

    Guidelines for Safe Motor Temperature?

    I found some data courtesy of Justin at Grin Technologies and he ran a MAC motor on his dyno at 150C without any signs of degradation. The problem I see is that as the motor temperature increases, there is the potential for thermal runaway...so if you can monitor your motor temps, I'd probably...

    0.27mm Thichness Motor Stator Laminations - MAC Motor

    Where can I buy a MAC motor? As of July 2020, EM3ev no longer sells the MAC. I want to buy a 10T and/or a 12T MAC. IMO the MAC is the best ebike motor available if used properly...peak torque can exceed 180 NM using a 52v battery and a 50A controller but continuous power can not exceed...

    Juiced Cycles with 12T MAC motor @ 48V doing over 30mph

    Excellent advice. IMO a 10T MAC or GMAC is the best option for 90% of those looking to build and ebike. The MAC has more torque per amp than any motor available. Get the MAC from EM3ev or if you want regen, get the GMAC from Grin Tech.

    The Best EBike Tire(s)

    Schwalbe Super Moto-X and the Maxxis Hookworm work best for me on harder/smoother surfaces. Off road...the Maxxis DHR II on the rear and DHF on the front.

    Guidelines for Safe Motor Temperature?

    Just hypothetical on the 24 hours...wanted to fully express that I meant long term and not transient temperatures :) .

    Guidelines for Safe Motor Temperature?

    All great and wonderful information BUT for a MAC geared hub motor for instance, what is the highest core temperature I can have for 24 hours straight without any degradation to any of the motor components? Being a scientist/engineer, I want a specific number instead of a range :). If a...
