Velorex Upgrade

Page 1 of 4Next

I was asked by a member on this thread to send some pictures of the upgrade kit that Lonnie Cook used to make. I cannot get the private message portion of this site to accept a picture. I will try to send them here.

Well, I didn't ask for the pictures, but I sure appreciate you going to the trouble to post them. I too, am picture challenged on this forum and another for old Hondas.

I have a Velorex 563 and plan to upgrade the axle to a 1" so I can mount a H-D spoke wheel and disk brake. After seeing your pictures, I believe it won't be that difficult to fabricate. Thanks...

Later, Bud...


You are more than welcome. Just trying to do a little pay aback for all of the great help I have received on this forum.

The kits that Lonnie Cook used to make were really good (I think). He was also very generous whenever I called and asked dumb questions. A good man who will really be missed in the sidecar community.

I had him install a Velorex on my Triumph T100 almost four years ago and it is still tight and runs true down the road. Definitely will be missed.

Thanks guys! It was me. Sorry for all the problems. I'm actually getting stuff from both of you, how interesting... Seems we all have Velorex in the garage. 🙂 I also asked Lonnie a few dumb questions, unfortunately I didn't really find out about his conversion until he only had one left, and he sold it before I decided for sure I wanted it. It might even be the one on Mike's car. Anyhow, in the spirit it was meant, I'm for sure willing to share all of my misadventures when I finish them. Reverse engineering Lonnie's invention is only possible because he did it ITFP.

It looks so much neater when you put all the pictures together.


Now if we can get all the Velorexs together we'll be in good shape.


🙂 I think we might be already here... LOL
Thanks again!

Just to reiterate- it looks like I didn't mention in this particular thread- Lonnie Cook came up with this idea, and I'm trying to use his idea. It's a great idea. Lonnie passed away, or I'd probably buy one of his already made. Shrug. I like tinkering, thanks to him I know it will actually work if I do it right. (Big if.) Rest in peace and thanks for the help you did give me, Lonnie. 🙂 I will try to share my results as much as he shared his knowledge. I need to take some more photos so it can maybe be another article in the mag... I think he'd like that.


Send me your address and I will ship the old swing arm to you.
Then you can figure out what you think it is worth.

Some random ramblings on the subject of Velorex sidecars and up grades to them.
Lonnie copied Doug Bingham's set up. This has been done for decades. It is nothing more then putting a trailer axle in place of the Velorex axle. It moves the weak point in the system to somewhere else as the rest of the sidecar is pretty light duty. With this set up many people are tempted to put the sidecar on far to large of bike some thing I do not recommend even with the up grade. What I have often wondered is why with this set up no one has ever also gone the next step and added a brake? I suspect it is due to trailer type drum brakes are two strong and the trailer type disk brakes are far to large. And for most people making their own hub and coming up with a proper disk is an issue. We can supply a hub with a brake rotor that fits on the 1 inch axle, we can supply a mount to attach a brembo caliper to the swing arm. We carry the calipers and can make brake hose. We sell this as an up grade usually for California sidecars for $650. In the case of the California sidecar as would also be the case with the Velorex the caliper has to be mounted up side down on the bottom of the swing arm in order to work with the fender in place. As such to bleed the brake you have to remove the caliper and turn it over, bleed it off of the sidecar and then install it. So, I guess my next question is as both Lonnie and Doug are no longer with us offering this up grade. Is there a market? Should we now offer it? If we did we could offer it with a brake installed. We have a Velorex (for sale) here that we could use to develop these parts that we took off of a bike and mounted a sidecar much easier to get in and out of onto a Triumph T-100 which for what it is worth was installed by a Velorex dealer in the NE who did an exact copy of our mounts so as to not have poorly fabricated parts that look exactly like ours we took them off the bike, tossed them in the trash and replaced the mounts. (BTW thanks to the dealer that not only stole our design but also caused us to give away a set of mounts) We first fixed the mounts on the Velorex by up grading them to the system as shown at this link as the hardware on the Velorex had slipped so much that the bike was almost not ride able. (we offer these up grades as a kit as well) They then tried the Velorex (they had purchased the bike sight unseen on line) and found it to be to small and hard to get in and out of. They now have one of our M72D sidecars on their bike. We also took the steering damper off the bike that the Velorex dealer had installed in order to hide the problems with the mounts and we installed a new set of triple tree's to lower the steering effort.
