Re: FUTR Beta with Lightning Rods Mid Drive

Pretty much any bike shop. It’s a standard BSA thread 68mm BB. The most common kind.

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

This drive has no freewheel to break. Because of that it’s compatible with regen braking. I realized early on that my customers were in two groups: people who want to pedal and people who don’t. Pedelecs like the Bafang are designed to be low powered drives that the rider can pedal with. That’s what...

What do you have in the works Mike?
Two stage left side drive, new motor, not on swingarm, ASI BAC4000 controller, shooting for 25kW. :twisted:

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

I personally prefer the Qulbix over the Enduro. The pedaling position is much better on the Qulbix and the build quality of the frame and especially the swingarm is on a much higher level. The Qulbix is a couple hundred more and well worth the extra money. The Bafang HD is a nice pedal assist and it...

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

The motor on the EEB actually is very close to the same height as on the Qulbix. The reason that it looks like it's lower is that the bottom bracket and chainring on the EEB sit way higher than the Qulbix. I'll attach a graphic that shows the layout of the two bikes in comparison with swingarm drive...

Re: LightningRods mid drive kit

Hey, thanks for asking about the Motoped. It’s still in the shop. I’ve purchased a 15kw capable Golden Motor, a 300A+ capable ASI BAC4000 controller from Alan Hu, and a 200A capable 42Ah 18650 custom battery pack from PowerVelocity. I’ve figured out where everything is going to go and how I’m going ...

Thanks. It makes sense. You can get LiPo in lots of sizes. Something has to fit the Beta.

Re: LightningRods mid drive kit

I’m glad that helped. I’m happy to answer any questions. The through bolts with Nylock nuts are the most secure way of holding the drive together. The side plates are aluminum to save weight. I wouldn’t trust tapped threads in aluminum with the torque necessary. I could use threaded standoffs with m...

Re: LightningRods mid drive kit

I'm not sure if you wanted feedback from users or the builder (me). Here's my .02c worth. The idea behind the Single Stage is that there is no other reason to reduce motor rpm to 100 at the chainwheel and then overdrive it back up to 400 at the rear wheel other than to match motor rpm to rider pedal...

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

Hi Doug, Yes I was referring to buying a mass produced freehub that's undersized. You would have some things to work out in order to get all of the spacing correct. The brake rotor is the most critical bit. My hubs are a lot more sturdy and have sealed motorcycle type wheel bearings rather than bicy...

Re: LightningRods mid drive kit

The problem with the scenario that you suggest is that with a bottom bracket drive the motor rpm and pedaling rpm are tied together at the chainwheel. It wouldn't really do you any good to have separate sprockets at the back when they're connected at the front. The options to this is to have a long ...

Re: LightningRods mid drive kit

Right. This wouldn't be hard at all to do on a through axle bike with a horizontal dropout. On a typical vertical dropout bike with quick release hub we'll need the right end spacers and some form of tensioner. It's a lot easier to manage chain tension on a single speed than a cassette. The chain gr...

Hub motors are great for cruisers. They’re simple and very quiet. I don’t like the handling on dirt bikes with hub motors.

Re: LightningRods mid drive kit

That drive was a prototype that I developed for a Belgian company that was wanting to build their own ebike based on the Ruff frame. I don’t know where they are in their own development process. The motor power did not go through the gears so there should not be any durability issues with the IGH. T...

Hi Guys- Thanks for your posts. I get busy and I forget to post on ES. I do a better job of keeping up with my Facebook page these days. I am looking at RC motors. I'm also looking at larger, heavier motorcycle sized motors ranging up to 30kW in power. The venerable small block and big block are als...

Let off the throttle when you shift and I can’t imagine you’ll have any trouble with the Rohloff.

Looking around, I do see a potential candidate - the motor mounts are deteriorating quickly: That broken rubber mount is not making that sound.

I've never had a customer break one of these Rohloffs, even with the plastic shear pins in them. I'm pretty sure that Erik stepped it up to the aluminum shear pins.

yeah, I haven't ridden it yet - but the throttle feels really silky smooth. Did you watch the video with the sound on? Is that noise normal? It's really loud. No that's not normal. It sounds like one of the chains is rubbing on a metal part. Look around while you're running the drive and see if you...

Re: Surly Big Fat Dummy with L-R Big Block Mid Drive

I didn't even think about the nearly 5v full throttle signal on the Domino. That much voltage will cause Vad's controllers to go into fault mode and shut down. I'm glad that the inline resistor did the trick. You should have the smoothest, most progressive throttle possible now.
