    Added raised bar (no higher than original but flat not angled grips), 90mm 45 degree angled stem, and Ergon MP3 grips, (have MP5’s on my Thorn Nomad tourer). That’s me done for now - not now an MTB but really loving it as tourer/cargo bike and fun for a fitness ride if the bumpy bits are too...

    Decathlon Rockrider E-ST900

    Very basic questions....1. My grips are a bit lower than I would like relative to saddle (I need saddle slightly higher than normal due to stiff knee), maybe 5cm...can you fit spacers or would you go for riser bars / angled stem or a combination of the two? 2. Secondly how the hell do you get...

    Very pleased with Rockrider E ST 900, have read around on here and used the advice. Wanted an “e-SUV” for up to maybe 20 miles local trips for shopping, pub runs.etc in a hilly area, have a Nomad (analogue) tourer for when I want to beast myself. Changed chainring to RaceFace 38t, added pannier...

    Exactly the same today for me! Changed to 38t chainring, same issue but didn't need a soak but was very stiff. Also got tyres changed for £28.50 in total.

    I felt the metallic noise was in the motor not the brakes, changed the knobblies to Schwalbe Super Moto-X and it has gone completely, so obviously a resonance thing on tarmac....

    Rockrider e-st900 tyre recommendations.

    Using the bike almost all on tarmac and a bit of gravel have switched to Schwalbe Super Moto-X 2.8s, quieter, smoother rolling AND the annoying metallic noise than can from the motor are at around 25 KMH has gone completely, must have been some sort of resonance from the original tyres.
