    Mac hub help

    Hey all, wondering if you could help me out. My Mac motor seems to be engaged all the time. I took everything apart and opened up the motor, gears seem fine, not sure about the clutch as I didn't know how to dismantle that. Nothing is connected to the bike, the motor would normally freewheel...

    Wood Frame Battery & Controller Case - heat question

    That is not a bad idea moving the controller to the back. I will see if it fits. I may not do a fan, maybe an "L" shaped black pvc pipe or something similar for an intake. That would help cool the controller and let out any moisture that gets in (also I would seal up the other holes as I am...

    Wood Frame Battery & Controller Case - heat question

    I should add that I wont push more than 15-20ah (1100 watts peak) and I live in Seattle, so it's cooler and err rainy... Hopefully that'll keep the heat down as well. Thanks for all the suggestions!

    Wood Frame Battery & Controller Case - heat question

    I've done some more updating and am fairly happy with how it turned out. I should add that I choose wood because I don't know much about other materials, so it seemed easier. Next steps - Testing: -Figure out heat control. If needed cut out the top portion to have the controller sticking out...

    Wood Frame Battery & Controller Case - heat question

    I have a 20" Ogre. I can't move the controller up because of the battery, it's a tight fit. (Cellman's battery is quite small for the watts you get, I am happy with it). I thought that putting the exit hole in the back by the controller would force air to flow by the controller either way. I...

    Wood Frame Battery & Controller Case - heat question

    I'm close to finished with a wood battery frame case, more pictures to come. My goal was to have a more secure waterproof case than the standard frame bag. Plus I wanted to fit the controller inside for a cleaner look. It will be stained black and some waterproofing sealent added. But I'm...

    Chevy Spark EV

    Seems like consumer reviews are good from the owners in Cali and Oregon (huge fun factor). We are supposed to get them in Seattle before the end of the year and I plan on leasing one for the lady. $999 down and $200/month is what they are currently going for, it's nice that the dealer takes...

    Selling built kit bikes locally?

    I live in Seattle where there is a huge biking community. Just for fun I was thinking about buying decent used bikes from Craigslist, building up a Mac kit on them and then reselling them on Craigslist for a minor profit. I'm not looking to make huge money, it's just fun building up bikes and I...

    Surly Ogre Mac 500W build

    I'm the OP. In the ogre pics above you can see how the wires from the controller are going right in the bag. I feel that won't be very water proof.

    Surly Ogre Mac 500W build

    A problem I have been having is with the frame bag. I would like to both secure the battery and controller from theft and also water proof the system. Right now I have been running all the wires through the frame bag, but I'm afraid that water could run down the wires from the controller into...

    Surly Troll - HS3540

    Nice work, I really like the clean look. I did something very similar with my Ogre, but decided to center the weight with a frame battery and used the stock frame instead. I do find that the suspension from the fat tires are enough along with the thudbuster, but my roads are not that terrible...

    Surly Ogre Mac 500W build

    Thanks for the feedback! The bike is more upright but that is because of the stem, not the Ogre's riding position. The Ogre itself is more of a hybrid between the two and I have actually done both Mt. Biking and Touring with it. It's been a work in progress as I have a hard time making up my...

    Surly Ogre Mac 500W build

    I've been reading this thread for about a year and would like to thank everyone for their support to this website. The creativity that you all have is inspiring. After a lot of planning, I choose to build a functional commuter that could handle hills and heavier loads. I do not have a very...

    Ready to order - Help with my Mac EM3EV (cellman) build

    Nice, I have the same thing but a 9fet from Cellman, works great. The 10T does good on the hills in Seattle and the 50V 20Ah triangle battery (NCM) fits fine in my Surly Ogre triangle frame. I get around 18-26mph with 29er wheels, depending on hill and gear. I get about 30-40 miles on 10Ah...
