    Thanks, I am just trying to find out if the spokes I have coming (155mm 165mm and 175mm) will be in the ballpark. I don't get pissed at friends I ask for advice in good faith, if you say your spokes are 163mm, I am not going to go and buy a bunch of 163 mm spokes .... your hub may be different dimensions to my Violamart hub motor, your rim may be different from my Chinese fat bike rims... there may be a different amount of 'clocking' of the motor to the rim, meaning I need longer or shorter spokes than yours.


    If you can say your spokes fall between 155mm and 175mm that would give me an indication if the spokes I have coming might work... I have some 10mm, 12mm and 14mm nipples and nipple end washers coming too, which may or may not be needed.

    I would appreciate if you could break your rule and let me know the length and if the drive side and non drive side are the same or not... purely out of interest, NOT to rely on your measurements to copy

    That is the kind of question that needs a lot of information to answer correctly. Even if I had that information I wouldn't tell you because if I was wrong you would be pissed at me. I will give you the link for the calculator that I use.

    Our handy spoke length calculator allows for easy calculation of spoke length for custom builds - and is the only one of its kind to include paired spoke holes in the flange as is common with many large diameter hub motors. It also creates an automatic side view drawing of the laced wheel and computes the spoke nipple angle where it enters the rim. There is a drop-down list of many common hub motors and rims, and you also have the ability to measure the hub and rim directly and plug-in those numbers if an option isn't listed.


    Go over the whole page. There are some links to some videos............hmmmm maybe I can find one. https://www.youtube.com/watch?v=3OialWggZJo

    Here is the bike on the beach at Fort DeSoto park south of Tampa near St Pete.

    Blue water Blue sky, this was a great ride. It was a little short though at 12 miles and it takes me an hour of driving to get here from where I am staying north of Tampa.

    Here is the other side. Those extra hole are the remains of that 5 speed Sturmey Archer installation.

    "I'm interested in doing a mxus build for this bike. I've read your threads a couple of times and I don't see where you mention using any torque arms. What did you do to secure a big hub motor in an aluminum frame or is your frame steel? The current Lux Fat Tire 7D is aluminum. Thanks!"

    Comments can get lost in the weeds so to speak and I almost lost this one. It is better add an entry or quote something because it shows up better. Anyway torque arms.

    When I had the Edge on the bike I used Torque arms made by Grin.

    https://www.ebikes.ca/shop/electric-...orqarm-v4.html



    I only used that piece that fits the axle. I put one on each side and I pushed one forward and one to the back and drilled a hole in each flat rear dropout plate for the nut and bolt. Then when I switched to the Mxus motor those arms didn't fit because the axle is larger. It is still 10mm across the flats but it is 2mm larger in diameter or 16mm. So I bought arms from West coast cycle.

    https://west-coast-electric-cycles.m...-m16-m14-axles

    Then Miracle of miracles the holes I drilled for the other arms perfectly lined up..

    After building several bikes I have decided that you should get your rear wheel spacing, freewheel, chain, and all correct before you lace your wheel. Then you will know exactly how to dish your wheel. The factory bike had 26 X 3.5 fat tires and then when I changed to 26 X 4.0 knobbys my chain was hitting the knobs. Those torque arms can be used as spacers on either the inside or the outside while you are setting up your stack.

    Everything was fine until I got my regen working. The 45 mm Mxus motor produces an insane amount of braking. It was almost like slamming on the brakes without dragging the rear wheel until I toned it down by reprograming the controller.. The constant change in direction of the applied torque had the axle nuts loosening up. there was a lot of creaking going on back there. The answer to this problem came from Mr. Bill over on endless sphere.

    bicycle photos, bicycle tour narratives, photos, ebike


    I installed a couple of "NordLock" washers and tightened the heck out of the axle nuts.

    https://www.amazon.com/Wedge-Locking...6719903&sr=8-1

    I also got a decent set of axle flange nuts instead of the crap that comes with the motor.

    The regen is worth all of the trouble it caused. 95% of my braking is done with the micro switches built into my brake levers. I will see if I can get a couple of photos tomorrow if I don't forget......calfee

    PS I'm thinking of building another one. Only with the Tall steel frame and a 6T 35mm motor. The tires will be Schwalbe 2.8 X 27.5 Super Motos. There may be some welding involved on the rear dropouts and the head tube for the suspension fork. I have ALL of the parts except the frame. A new tall cruiser in steel is less than $400. Right now this bike is in my head. We will have to see if it ever gets out.

    Well I needed to do some maintenance before Florida this year. The bike also had a clicking in 4th and 5th and the chain would hit the tire in 7th so I ordered a new derailleur. I also have an eight speed freewheel that I will use the top seven speeds and leave the largest sprocket like a spoke protector. I am going to change my spacing in the back to see if I can get my seventh speed back.

    I am also going to abandon my tubeless tire setup and go back to tubes with Stans in the tubes.

    Well this was a good upgrade. The new derailleur and chain are working flawlessly and my chain is just barely touching the tire when I am in first. Both up and down shifting while pedaling feels like an automatic. Shifting while pedaling keeps the power uninterrupted and the flow of the ride is much better. This bike is ready for Florida now.

    Calfee20, what is the motor winding on the MXUS 3000?

    Nice build man! You must have built a few bikes, it looks real good. I am totally new and for my personal bike I am looking to get a set up like this. I am just to green to jump that deep at first. But I am def going to go back thru your thread to get info. Maybe I can find a builder here in FL to help me put the parts together.

    I must have hit on a perfect combo with this bike. Since I installed the Maxxis Mammoths the bike has gotten incredibly efficient. I was not looking for this. It just sort of fell into my lap.

    I went on a relaxed 40 mile run with my oldest daughter. She was riding my BBSHD Electra Cruiser with Schwabe Big Apples. It was a good mix of paved streets and bike trails for this area and I got 15.5 Watts per mile!! If I am by myself and going a little faster I'll get about 17 Watts per mile but if I am going still faster and doing a lot of sand ,mud and off road it won't get worse than 19 Watts per mile.

    My batteries total 31 amp/hours and if you figure out the watts available and use a conservative 20 Watts per mile I come up with at least 110 miles. The only explanation is the center strip on the tires that the bike is running on and maybe I have hit on a perfect combination with this motor winding and tire size. I can pedal this bike at 25mph with 500 watts of assist. It does not make any sense but I love it.

    I installed Nord-Lock washers on the rear axle and toned down the regeneration so everything will stay tight back there. I'm hardly using any brake pad material at all. 95% of my braking is done with the regen. This is another big plus

    This is the end of the Fairhaven Bike path. I am standing on top of the Hurricane dike. My back is facing the mechanical gate that the boats go through. The harbor is on the left, Buzzards Bay is on the right and that is Fort Phoenix with the cannon on the right.

    This is from the same spot but facing the Fairhaven side of the Harbor.
