Over the years I have pretty much ridden every style bike. This is my second ebike, the first one was a cheap Walmart FS bike. It is just like dogman's green one. To be honest, with the batteries on the rear rack, it scared the shit out of me at 30mph. The components were crap, brakes would hardly stop it and it didn't take bumps very well. Even after I up-graded a lot of the parts it still felt unsafe.
The Townie is a whole different thing. Out of the box it felt solid. I liked how the longer wheelbase handled at speed. With the new fork it takes the bumps great (the original forks were fine too). Even though it doesn't have a rear suspension the seat post and Brooks sprung seat make for a plush ride ( the 2.5" hookworm @40 psi helps too
As to the Thudbuster, I'll never own another hard tail without one. I have tried both models. The long travel (LT) does a good job. It has more travel than the ST. Both come with a variety of elastomers so you can adjust the hardness to whatever you want. I ended up with the ST model because I wanted more seat post length exposed so I could mount a rack to hold the aux batteries. That is also why I bought the sprung seat. The combo of the LT thudbuster with the weakest elastomer and the Brooks saddle turned out to be perfect for me.
I got most of my replacement components at half price. Be patient and eBay and pinkbike can save you a bundle. For example, the Thudbuster and Brooks saddle retail for over $300, I managed to get both for about $120.
