Radwagon weight limit
« on: September 04, 2021, 11:46:37 PM »
Hello, anyone here exceeding the weight limit on the Rad Wagon? I am looking to buy one and am a big guy and have stuff to carry. There will be times when I will exceed the 350 lbs. I will be on mostly flat ground but I am not sure what the weak link might be? The geared hub, the wheels, the frame... etc? Anyone have any practical experiences?

I am willing to do a little re-engineering if I need to but am hoping to find out in advance what might break first.

Thanks in advance

These guys did a fine job of building the RPW4 frames!  It has all quality TIG welded frames. I'm not a ME or CE but I have a background in Manufacturing Technology.  You'd be best to probably just call RPB's to start. 

They know the "intended" loads the frames were designed to.  Designed loads and possible loads are usually far apart. You have to know wall thickness and weld penetration specifics to do a full engineering evaluation.  The angles and tube OD's you can do. Most 3D design & modeling software includes some type of load analysis.

The ID's require some designer-specific engineering knowledge unless you have an x-ray or ultrasound device able to take those measurements. 

A Sawzall could give you quick ID's, on the tubes, but much poorer bicycle performance!  (kind of...LOL)

I'm an RW4 owner. I'm not using any of these ancient forums. (ICQ, AIM, MSN, YIM). Instead look for @joelhuebner, joel.huebner,, joel52334.
That's where you will find me.
