Since I haven't seen a review about the new Moulton TSR-2, I thought I'd write a few words of my impressions.. I'm a big fan of 2 speed kickback hubs.. I like belt drives .. and the Moulton spaceframe models are my favorite bikes to ride .. so, the announcement in late 2009 of the belt drive Moulton TSR-2 seriously piqued my interest.. In late 2010 a few trickled into the US.. I got the first ones off of the boat and filled my pre-orders .. our most notable of professors flew out from Chicago to pick his up.. I kept one to put some miles on and provide demo rides.. other than a change of tires to a little wider Primo Comet (42x406) to allow me to ride some of the dirt trails in the area, the addition of lights, mirror, and tool bag, the bike is basically box stock..
The TSR-2 uses the new Sturmey Archer S2C kickback coaster brake hub... the belt drive system is from CDrive, which has provided it to a few OEMs wanting to implement the system on their bikes .. it is not nearly as expensive as Gates Carbon Drive, and as such, can get more people into belt drive technology at a lower price point.. gear inch range with the stock Continentals is approximately 50 to 70 gear inches using a 67/25 sprocket/cog.. with the change to the larger 42/406 Primo Comets, 52/72 gear inches.. that's very close to what I'm used to with my Dahon Mu at 54/74 and my converted Titanium Douglas at 56/76.. the frame is almost identical to other TSR models with the exception of horizontal rear drop outs, a split in the seat stay to allow belt installation, and an absence of rear braze-ons and cable stops.. it has a very clean look and handles the same as the rest of the TSR family.
So what do I think after 250 miles of use in moderately hilly Marin County, CA, all in all, the bike is a pleasure to ride .. I've been trying to push its limits, out of saddle uphill sprints and hard use of the coaster brake on the long downhills ... the TSR-2 is ultra simple, no cables to the rear, no shifters, and the belt drive is silky smooth .. it's biking in almost its most basic form... the Sturmey S2C is new to the market and doesn't really have a track record.. the coaster brake is powerful and will lock the rear wheel up instantly if you don't modulate the pedal pressure with care .. it is much more sensitive than either the Sachs, Shimano or earlier Sturmey units that I have used.. I'm sure as the parts continue to wear in, the abruptness will smooth out... the hub shifts by back-pedalling a few degrees and then proceeding to pedal forward.. there isn't much room between shifting and starting to apply the brake.. it's a knack one gets used to after a few miles.. having a 2 speed, belt drive, full suspension bike that separates in half might seem like an odd combination to some, but in actual practice, it should find a few happy cyclists wanting a bike this simple, clean, quiet and comfortable.. I like the TSR-2 a lot.
