P.S. Returning to photography :) 'Six Seconds Of The Life Wasted' :)

I have no slightest idea how Mahle calculated that. Let us assume a tyre of circumference of 2,250 mm or 2.25 m. Also let's assume the rider travels at 32 km/h, or 32,000 m/h or 533 m/min. The wheel rotational speed would be 533 / 2.25 = 237 rpm or 24.8 radians/second. I absolutely trust the 275...

So guys, I got me a Cotton CCS G3 harness for 1 camera. (A French product. Whatever is shipped by courier from France to Poland takes over a week!) I could immediately spot a design glitch of this gear. The mounting system here is called Twist & Lock. You are expected to position the camera...

Schwalbe says no winter bicycle tyre makes sense unless it is studded :)

I know another saying: "A cow would not become a horse even if it stood by the horse for 20 years" :)

I'm always interested to hear the Peak Power and Max Torque mentioned in one breath. Rear wheel RPM = 275 W / 65 Nm = 4.23 rad/s = 40 rpm. Now, assuming the gearing at speed might be 4:1 (chainring/cassette sprocket), what would be the cycling cadence? Or, are the Peak Power and Max Torque...

Whatever I say or whatever wildtrack or the two Bosch representatives on these Fora had ever said won't convince you Johnny so I give up. Whether Bosch cannot or will not change the upper speed limit, the fact is the CX is and will be Class 1. Bosch SX might be Class 3 depending on the e-bike...

Are you planning to go tubeless with them? (The price in Poland is around $30).

What Spec tyre model and size?

I had a situation on my Tuesday Warsaw ride. A pipe had broken beneath a street, which created a huge and thick block of pure ice at the crossing, just across the bike path I was riding. I noticed the ice too late and rode onto it. Scared for a short while, I thought "Why worry? You ride on...

Bosch cannot change the region or class. Bosch motors are manufactured in Hungary. When an OEM such as TREK needs, say, 5,000 motors for the region of the U.S., these numbered motors are hardcoded for the region. Why wouldn't Bosch, OEM, and the dealer agree to change the motor's region if that...

OK, Ras, I could not handle the 42 mm Rhombus or Tracer together with the rear Speedrocker on my Vado SL. I gave the rear mudguard to a friend and installed an Ass Savers Win Wing 2 instead. The problem solved.

Of course! However, do not expect a high speed on the flat. You cannot raise the top speed limit. Cat, please just confirm: Is your Bosch SX e-bike Class 1? I'm asking because I'm not familiar with this system.

No idea how you could fit a Byway and a Speedrocker on a Vado SL 1 frame size M as the clearance between the tyre and the seat-stays on that e-bike is very tight.

A nice lens, eh? :) Collected! -11 C again! 17 km for the day.

Not. It is a religion for Bosch. No other e-bike motor manufacturer has put in so much attention to prevent the motor derestriction. Yes, many people use SpeedBox. If they do it wrongly, their motor becomes a brick. I understand Johnny you simply cannot get it but that's Bosch E-Bike. What...

Glad to hear you could solve the case!

It seems to have warmed to -7°C here. A big deal! (Was -16 in the morning). Riding to collect my universal zoom lens from the service.

You are certainly a Bosch E-Bike technician to know all this, like @wildtrak was, Stomp. There were also Bosch E-Bike representatives in these Fora well before you joined. They were very specific: in case a 25 km/h Bosch E-bike were imported in the U.S. then NOBODY could change the speed...

Kevin, your English has defeated me (that is, I though I knew English) :) You said your experiences with Bosch were superb. Don't you simply think your expectations were rather low? To stay on topic: Do you own a Bosch e-MTB? What motor? What Class?
