Accesories and security: some non-standard measurements to be aware of.

Got my awesome Walleräng M02 from Tacoma Bike and of course it needed some accesories. Got new grips
with bar end, Ergon GP 3, got a Bush & Muller e-bike mirror shipped in from Propel Bikes and from Germary Pitlock security axle and nuts front (set 04) and back (set SH38). Also for the seat post set 14 seat post clamp and securing bolt. (31.8 mm)

Most of it went well. But the seat clamp pitlock does not fit, of course, because 31.8 mm is the diameter of the seat post, not the outer diameter of the seatpost frame tube. I don’t have a caliper but at the bike shop I was told that the correct size is 35.8 or 36 mm. Pitlock does not have this size available. Even if you try to use the 31.8mm clamp to block tampering with saddle screw (as suggested in Pitlock site) that won’t work either because the clamp has a lip that prevents it from going up the seatpost tube. At some point I will try to file this lip down and try again.

The real bummer was trying to install the mirror. The handlebar ends are quite narrow and the wonderful Bush & Muller folding e-bike mirror did not fit, actually none of the mirrors at the store would fit inside either. So I opted to change the handle bar. Great opportunity to get myself more upright. I got a handle bar with a little more rise and a 30 degree angle stem. Almost ready to commute, already gone from ridding 5 miles bored at gym to 20 miles with least assistance I am able to. Go ride!
