    PaulD's lightweight mid drive development

    I think the torque sensor might be better. I used the throttle for him because the bafang pas sucks. On the other hand my boy was riding a OSET 12.5 with a throttle before he turned 3. At that age he still could't figure out the whole pedaling thing. Maybe a throttle is better? Now these are out...

    PaulD's lightweight mid drive development

    Paul, I think there's a market for a smaller lower powered version of your system for kids bikes. I built a bike for my boy and made this video https://www.youtube.com/watch?v=K3BRabYe9yo. That bike was just a walmart bike but regular bike companies make some nice kids bike now. My boy was...

    BBSHD Transition Preston

    I built this bike a few years ago first with a BBS02 https://endless-sphere.com/forums/viewtopic.php?f=28&t=73635 then with a BBSHD https://www.electricbike.com/bafang-bbshd-1000w-mini-review/ I then put 575 miles on it all single track off road. I did those miles with a back pack battery (10 AH...

    Powder coating is the way to go. I got great results from a home powder coat kit I got from Eastwood Company.

    Andrew's LMX 161 Chain-drive massacre Build Log

    I use this method to get the ideal chain adjustment on my ice dirt bikes. I disconnect the rear sock while the bike is on a stand, then you can freely move the swing arm thru its travel. Chain drives want zero preload and just a little free play to work best.The chain will be tightest when the...

    New "Lingbei MM28.250 torque sensor mid drive"

    If there is a torque sensor, there must be some type of load cell between the axle that the pedals are connected too and the large gear that the motor drives and has the chain ring connected to it. Pull the axle and see if there is more than just a freewheel under there.

    What rear hub is that? OSET? LMX?

    I love it!!!! I think the swing arm mounted motor makes a lot of sense. Of course a small increase in unsprung weight but you can't beat the simplicity. The use of all straight tubing is fantastic and the use of 3D printed parts to jig it up is genius. Also, in the picture, where the frame is...

    LightningRods mid drive kit

    I agree entirely. This is why every motorcycle rear sprocket I have ever dealt with (and that’s a lot of bikes) has the rear sprocket bolted on. All have a hub in the center that supports the sprocket so only the shear force due to tourque is the only force that acts on the clamping force of the...

    new cyclone 3000 w mid-drive kit?

    I don't think that freewheel is the problem. The reason it works now is because when you eliminated the freewheel you no longer have the gear reduction so your torque at the cassette is greatly reduced. It's probably skipping on the cassette.

    Bikes Direct enters the eMTB market

    Wow! Love it! I'm an old dirt bike guy that moved to e bikes. Then I slowly fell in love with pedal only mountain biking. Now I really want a pas only low power e bike like all the OEMs have. This looks perfect!

    LightningRods mid drive kit

    I love your approach of creating different types of systems that have different strengths. My needs (single track only) are much different from someone who uses their bike to commute. With your expanding product range, your going to have something for everyone!

    LightningRods mid drive kit

    How about that single stage set up run single speed but on the left side. The sprockets would be concentric to the BB but could ride on bearings built into the motor mount. Maybe one of matts adapters for the sprocket on the rear wheel.

    new cyclone 3000 w mid-drive kit?

    I had a similar experience with Kelly. If I called them during their working hours which for me me was conveniently early evening, Fanny would get back to me in minutes. It was more like online chat than Email.
