Tektro E Drive 9 (T530)

The Tektro E Drive 9 derailleur system is one of the earlier entries in the race to be the derailleur of choice for e-bikes.

Some of its features might include:

  • Being a 9-speed system, because this allows a wider chain and sprockets (for reduced wear under high loads) and e-bikes don't need all those ratios anyway.
  • Being 1X ("one by") because it's simpler, and e-bikes don't need all those ratios anyway (have I said this before?).
  • Being a touch on the heavy side - as, on an e-bike, strength is more import than weight.
  • And probably something else...

Regular readers may notice that, amazingly, all these features are shared with most mid-range derailleurs from most of the world's manufacturers. But I expect that we will see the letter 'E' and some variation of a lightning flash logo on many derailleurs over the coming years. At least Tektro can claim an early lead in the branding stakes.

Aside from the cynicism, the Tektro E Drive 9 is well made, sensibly and strongly constructed, and looks like it will give years of perfectly satisfactory service.


This example is the T350 'trekking' version, which has no clutch.
