Motorized Bicycle OVERSIZED TUBING solved

[Bikeguy Joe]

The modified mounts tend to work better than stock.
The original mounts are made for V framed bikes, and older, small tubing frames.
The irony is that the new bikes coming out of China have large, weird shaped frame tubes....

Joe do you mean one you build yourself or one you order any suggestions

 

[Bikeguy Joe]

If you read some of that thread, there are a lot of ways to go about a front mount...build or buy, the choice is yours.

To answer your question, everything has been great. It's held up nicely. The only thing I was worried about was vibration, but it's minimal IMO. I haven't ridden enough bikes to see whether mine is more or less the same as other bikes' vibration.

What is the recommended thickness of the steel plate that Im looking into getting along w/ a U-bolt for my front motor mount.

 

[noco]

that is almost identical to the universal mounting bracket that comes in most kits...i thought is was suck a strong design that i copied it is a thinner version for the other post to replace the chisy stock bracket

Folks, has the oversized tubing issued been solved? I've read through this thread and read all the great ideas. I personally lean towards purchasing a manufactured mount. I noticed the mount by Ridley but the money they want is prohibitive. I'm hoping the Manic Mechanic will stay in business long enough to build two for me but if not, I have to find some somewere.

I have two brand new Landmarks in my living room right now. Both of the bikes are laughing at me as I tried to figure out the downtube oversize issue. It was a heck of a rise in learning just installing the rag joint for the rear sprockets! Then the engine mounts hit me with another challenge. I will persevere however.


So my question is...which vendor actually is selling mounts for the common man now?

Thanks for any input.

Here are are a couple that I know of for 15 plus shipping. I had the same problem as well with the oversize tubing. I just used a steel plate and a 2" U-bolt. Works great

Hope this helps

Hi Nogoodnic, I have not seen a mount like that since 1999! (yours is better tho, because Steve used to drill 2 holes as I remember). Thanks for the memories, Amigo! I hope things are going well for you, I haven't talked to you in a long time, is PA close to you? If so you could maybe meetup with Chris, Jim, and Jay, and see their EZM's.

Back on page 5 of this thread I posted a photo of a clamp on front mount for a Schwinn Jaguar. Here's one of the same design but a welded mount instead of clamped. Sorry no photos of it painted. The bushing is polyurethane automotive suspension part. Very very firm, not rubber. The aluminum cap was just something I did on a lathe.

aaaand I think I'm gonna steal that mount design for the Rollfast

Thanks 2door

Geoff,
Here's a better picture with the mount disassembled so you can see all the parts. This is the clamp-on but the welded one is the same thing.

Which is one of the things that caught my interest... not that I really need it - but you wouldn't happen to know the part number or specific application for that bushing wouldja Tom? It's no big deal as ofc I can just bring in measurements, but the guys at the part stores around here tend to crazyeye if you don't have exact year/make/model when yer tryin' to buy stuff...

It only gets worse if I actually dare tell 'em what I need the widget for
