Trek Rail Gen4 vs Gen3

[Juanroberts]

Is there a way to get the Gen3 to produce 340% pedal assist?

I ask because the pedal assist for the Gen4 is at 340% whereas it is 300% for the Gen3. The Gen4 has a 100 day order wait time, whereas the Gen3 is available to ship. And the Gen3 is about $2,000 cheaper.

Thanks!

Rail Gen 3 owner here, the pedal assist is 340% for both Gen 3 and 4.

The CX race on top line Gen 4's has 400% for short periods

Not sure why you asked this in the derestricting forum as most smart systems cannot be derestricted

I asked because derestricting is not restricted to only speed.

Bosch gen 4 cx motor.

Hi.all the talk is about the new gen 4cx motor in mtbs.i still haven't bought my ebike yet which will be a step thru of some type.can we get the gen 4 cx in a step thru and if not why not and why is it exclusive to mtbs and not trekking/commuter bikes.for instance Chris nolte done a review on...

“The biggest thing for me was the pedal resistance which is almost unnoticeable in gen 4 but it’s like hitting a wall on gen 3, also it’s lighter and smaller. It provides the same amount of torque 75Nm but gen 4 provides 340% assistance in turbo while gen 3 “only” goes up to 300%.”

Sorry I misread what you asked. Its complicated by the fact Trek produce the Rail in Gen 3 and Gen 4 which is what I was referring to.

But it sounds like you are talking about Gen3 and Gen4 Bosch CX motors, which do have differences.

OP, what display is on your Gen 3?

 

[Juanroberts]

I was waiting for a Rail Gen4 that was going to take 100 days wait while a Gen3 was ready to go. I was tempted to cancel the Gen4 order and get the Gen3 quicker. But, last week the Gen4 arrived after only 30 days. This was consistent with what Trek had previously said that they tend to underpromise and overdeliver.

Now I need to figure out how to load on the bike a first aid kit, inner tube, tools, etc. I do not like carrying stuff on my back. My prior bike was a Specialized and all this went inside the frame. The world of ebikes has a battery inside the frame instead.

Thanks.

(IIRC) went from Bosch CX Gen2 to Bosch CX Gen4 (never was a Bosch CX Gen3 motor).

Hello, my gen3 just had a problem. I saw that you said to upgrade directly from gen2 to gen4. If so, do the motor cables and controller (LED Remote) need to be replaced? I disassembled the motor today and found that the power connection hole of the gen3 motor is round. I don’t know if the gen4 is universal. It’s hard for me to find a channel to buy the corresponding motor online. If you have time, can you help me? Thank you very much!

I said that I don't think that there ever was a Bosch CX Gen 3 motor.
