Hi Eschurma,                                                                                                      8-5-21

Just got my Zoom 30.9 mm suspension seat post for my Radwagon4. It is a snug fit, but it did work.  TIP: put it in the freezer for a couple of hours and it will slide in more easily.  I tightened it up and it is all good.   Relatively inexpensive (about $30 on Amazon).  It is a simple spring, no parallel arms or articulation of any kind, but it seems to work. 

Be well, Stay well,

Thanks Wkin and Comm,                                                                                                             7-30-21

What you mentioned is just the kind of real world experience reporting I am looking for..not an advertising video or theoretical claims, etc.  I'm looking to increase top speed and torque on my RadWagon4.  I'll keep poking around.  Thanks for the input.

Be well, stay well,

Hi All,                                                                                                          7-30-21

Can anyone explain the advantage of a Bolton controller over the OEM unit?

Thanks.
Be well, stay well.
