    The USA really needs to convert to Metric!

    Course English threads were for tapping into aluminum and fine for steel. With metric you only have fine threads which can more easily be pulled loose from pressure. Also I noticed the default hole wizard in SolidWorks and the standard for metric flat head screws is different from the actual...

    Greyp eBikes

    "If" it does have coil shocks they should be upgraded as that guy in the video going down the stairs was feelin it in his arms. Then buy it without the "Wall-E" (probe) side covers and fab some real cool CF one's. Then ride it in the street like most bicycles have to (that don't have bike...

    Which ebike can work stairs out?

    When my tire goes flat I have to walk the bike home or to the next stop. Maybe uphill. Then I walk along side and twist the throttle lightly so it requires no effort from me. Walk your bike up the stairs the same way.

    UK newbie needs advice on 1st Ebike Build.

    The 9 pound weight BMC Torque motor at 48v will fit that bill. I ride slow and pedal to save battery and get 19 watt hour per mile. Or go 30 mph no peddling and get 33whpm. And I can carry my bike up to my second floor apartment every day after work and I am 60 now. Speed is there when you need...

    UK newbie needs advice on 1st Ebike Build.

    Most of the bikes on this forum are illegal and in the USA we do have a 750w max. My buddy is putting bikes together in Ireland and can supply you with a ride on his bike. Also sell you any option you need like a laced rim with motor or just a motor and spokes. Controllers, batteries. He's about...

    lifepo4 battery for ebike

    Here is a meetup club in San Diego for ebikes. http://www.meetup.com/Electric-Bike-Club-of-San-Diego My buddy Hemdan is in SD and can share info and a test ride of his bike. We are in the Facebook ES also. https://www.facebook.com/groups/125035107565566/ I have some of these available...

    New guy confused beyond belief

    Dogman is right about the torque arm unless you buy one of those 250w motors. While testing my MERIDIAN TRIKE with a front 600w torque motor I ripped the steel fork apart. I know better as I have about 13 extra torque arms lying around. It was just low power testing. I since had the fork welded...

    New guy confused beyond belief

    I have been modifying this trike that belongs to my buddy. It is for sale at any time but since this video I've added two springs which allow the front half to spring back up to center. It has a BMC front torque motor. I have another motor available now. It's a V2T front. Twist or thumb...

    Why aren't Mac motors being offered more by Chinese vendors?

    I believe you are not correct here. The MAC is a copy of the BMC geared hub. The story goes back more then ten years now. Chandu Vanjani designs motors for many applications. He developed the geared hub for Currie bikes back then and as soon as the were being built in China the quality went...

    Enclosed pedal electric tadpole trike

    Unfortunately jmygann is no longer with us. He was supposed to take delivery of an ELF but I do not believe he got to enjoy it.

    I'm new to electric bikes and would like help choosing a kit

    Check out Boostbikes in Ireland. He has a 9 pound (weight) speed motor that he just ran at 50 mph. It's laced to a rim and ready to go. He has Torque motors also that we both prefer. He has controllers also. I can get Nickel Magnesium Cobalt batteries also...

    Help me design a City Slicker Special

    With a little work you can hide most of the wires. I have a 5 mile ride to work so I use a 12s1p. I can fit 12s2p in that tank on the Indian bike. Wires are in the oil can. This is lacking the Cycle Analyst, suspension, and decent brakes but it also sticks out like a sore thumb to where if...

    Schwinn Trike Leaning test

    One leaf sounds easy to mount. Just clamp it to one block about an inch up and let the leaf ends touch the other plate. Distance of deflection would be an inch. Leaf spring length would be 4". Lot of force needed to lift the bike back up. High pivot no problem. Lowest pivot it would have to push...

    My bad Mike, I should have posted in EV's and not bicycles. Good answer but add cargo hauling, old timers.

    Schwinn Trike Leaning test

    Did you see in the second video how the lowest pivot line (inches from the ground) keeps the front tire in the same path as it is when straight up. Torsion bar is an idea I kicked around as I had them on the front of an old Plymouth. I am not going to dump a lot of money in this. It seems to...

    Schwinn Trike Leaning test

    John, I was aware of the pivot line not being at the center of the front axle. First test told me it didn't matter. And it seems like it will handle high speeds better then low because the rear drop increased the rake. Now it is sketcky to turn at slow speed. If I could turn the fork around it...

    Schwinn Trike Leaning test

    Mike, 26/20's. The frame does not look level in the stock photo but the basket does. So now it's 3" lower in the back. Now it looks level. Even the deck looks level. It may be another simplw challage to put a big ball diff and split the axle and drive the rears with a mid-hub. There is so much...

    Schwinn Trike Leaning test

    an extra 200 lbs on the flat should not be a problem. I am just making this available for sale but the looks are important to do so. When finished I won't feel humiliated to ride it. I am working on the springs/dampening to limit the lean (not to hit the bed). Feel free to improve your trikes to...

    Schwinn Trike Leaning test

    Changed the handlebars. Turned the neck around. Sissy bar coming and will bolt where the mid drive axle is. Kicking around the slotted side panels of the deck at the back. Second removable deck will be at the bottom near the lowest bar. The LiFe batt will be back in there. That mock up panel...

    Schwinn Trike Leaning test

    With bearings you could turn that center shaft into a drive shaft with a couple of bevel gears. I am trying to keep it simple and low cost. After I reduce the rake I will determine the extent of the lean needed and stop it there. I can then decide on the belts or drive and the distance for the...

    Schwinn Trike Leaning test

    I am thinking of a belt with tentioner that can be a fix for proof of pedal to the law. I just took the two sections of the trike apart and added a .75" diameter steel shaft. I could go one more plate and add suspension too. Maybe a lockout to keep the trike upright instead of a kickstand. The...

    Schwinn Trike Leaning test

    If you haven't ridden one you don't know how bad they turn at any speed. I used a .75" diameter steel pin to pivot on my buddies bike. The rake is too much as I put the 20" tires on the back for stability so the front tire turns using the side of the tire. Need a bigger rim, smaller tire, better...
