Rockrider E-st 900 changes upgrades

[Gary Davis]

To avoid the Lever positioning Gary has:



I am looking if our levers our compatible with both 2- and 4-piston calipers.

This youtuber talks about his new XT 8100, and at 1:04 he shows the box that indicates the XT levers are compatible with the corresponding XT 8100 2-piston and XT8120 4-piston calipers.
And at 2:42 he shows that Deore 6100 levers are compatible with the corresponding Deore 6100 2-piston and Deore 6120 4-piston calipers

Could our "Rockrider Tektro TKD32" levers fit the Deore 6120 4-piston calipers ?

Hi, I'm pretty sure there will be a compatibility issue with brake hoses. This happens even between some brake set into shimano brand itself. And yes, 6100 brake levers are compatible with x120 calipers

I'm looking for the new display. Not cooked mine in the microwave yet (following the Bebiker's receipt)

You've done some good work again there Buddy, which will benefit others who own this model.
You should be on the payroll for Decathlon's R&D department.

Thanks. I didn't noticed that you sold your bike. What's the new one ?

i'm still a st900 owner for my wife.. Decathlon Rockrider E-ST900 - EMTB Forums
but after this experience i've understood that 500wh was too much for me and my rides and that i was riding always in eco and eco plus. so i've switched on turbo levo sl. funniest!

 

[Gary Davis]

I don't understand very well. you often rode in eco or eco plus (e st900?) and you choose a more powerful bike ...

 

[chamaruco]

turbo levo sl is a light ebike

Ok. You were talking about weight (big battery)

 

[chamaruco]

big motor big battery vs my needs

Big buddy,... I see !

 

[BeBiker]

The Turbo Levo (SL) full suspension is on my wishlist too, to keep the E-ST900 for shopping, kids, trailer, work commute, family vacations, small trips.

It Is what we did here.

If they ever read this tread: Offer the bike in chassis+motor only version, we'll choose the rest of the parts ourselves

Before buying the E ST 900 I was planning to build a complete bike from Aliexpress. Carbon or alu frame with integrated Bafang motor but global price quickly increased. I eventually realized that E ST 900 was a bargain even with some inconvenients.

same here, plus I wanted a jumpstart, to be riding the first day.

Instead of ordering, trying, sending back, modifying, downloading, ordering again, painting, ...

So so what is your take on the 29er
Is it worth swapping to one
I know at the moment these Sunrigle Duroc wheels are as rear as "Hens Teeth"

The fat front 27.5-2.8 ennoyed me a bit, so I changed to 2.2
But that made the front too low.
29"-2.2 put me back at the same height as original.

I found the 27.5-2.8 at the front only rideable when very hard inflated. A bit less pressure made them comfortable, but extremely Left-Right instability.

The 2.8 balloon was slower to react, and cut less in the riding surface than a 2.2

You can deflate a 2.2 much more to gain comfort, wirhout getting seasick. Both on 27.5" and 29"

Still happy with the Rekon 27.5 2.8 at the back. Both inflated and deflated.
If there would have been choice, I would have taken a 27.5-2.6

The wheels are available, the website says MTB-voorwiel 29" DUBBELE WAND SCHIJFREMMEN BOOST 15x110 DUROC 30

Looks like travel restrictions are being lifted now so very soon so the wife and me can go and visit her family, crazy haven't seen them since Xmas 2020 .
Is that bad thing

Hi,

I am new to this forum. I have recently purchased the RockRider eST900 and I am very impressed with this bike apart from riding on the flat and downhill.

After reading the opinions on this forum, I decided to change the chainring to a 38t one. I didn’t realise beforehand that this was quite a challenge!.

I took my bike to the local bike shop and they removed the crank arm fairly easily, then used the tool mentioned elsewhere to remove the lock ring. Then the spider should have slid off but was stuck solid, after several attempts they used some sort of bearing puller to remove it. Finally it was off but the chain bolts were absolutely stuck. The mechanic said that they had probably used industrial strength loctite when installing the bolts. A long soak in hot water finally released the bolts. The Deckas chainring I had purchased looked very flimsy compared with the one removed, I hope it is strong enough. The mechanic was concerned beforehand that the chain might not be long enough but it was just ok. Finally, I took the bike on a test run and it worked fine, the extra gear was worth the effort.

If you are thinking about changing the chainring then I would certainly recommend a local bike shop unless you have the knowledge and equipment to attempt it yourself. I was charged £15 which I thought was very reasonable.

38T Deckas chainring is fine. I've had mine on for over a year now and not had any issues with it. Tops out at about 28mph on the flat.

So guys
Has anything been happening lately with your bikes
I've ended up getting a Cube 140 stereo hybrid for off road and using my rockrider for road both bike just working out fine for what there set up for

How is the Bosch Perf CX Gen4 compared to our Brose-T ?
I'm really happy with the Brose, but also want to buy a full suspension.

Brose has a list of emtbikes with their motor, but in full suspension there's only choice between the funny looking BH and a few ugly others.
Maybe the rotwild ?
