IMO 4 things will affect the outcome.
1. Your weight
2. The elevation increase of the course
3. The course conditions (wet/muddy?)
4. The amount of time you have to finish in
50 Miles for me with some mild climbing would be a mix of Eco and Tour+ (mostly eco)
You’ve obviously got a major problem with the RIB setup. For what it’s worth I have a Gen 3 9.8XT over 18 months and 2700km of riding and never had 1 disconnect
I don't believe the member that was making them is doing anymore..
Also power cuts will not be solved by removing the lock, take your bike back to the dealer and get the battery mount / RIB system fitted correctly. More here Rail (750Wh) - Trek Rail 9.8 xt gen 3 and rib issues
Or just search...
The main differences are geo. Reach is 5-8mm longer, wheelbase is about 15mm longer, head angle is a little slacker and seat tube angle is about 2 deg more upright. You'll get used to it pretty quick
Talk to the LBS. A lot of the 2022 9.8XT EXE's shipped with alloy cranks. Most got discounts when they told the store or had carbon ones shipped out when available.
Should fit no problems on 750wh battery rail. As for sizes 230x57.5 is factory so you can potentially overstroke to 230x60 and even possibly a 230x62.5
HTH
This is a dealer issue.. particularly on a newer bike.
The error code from Bosch states
Error 503019
The motor control is not working properly.
This may cause the eBike to switch off automatically and mean that no motor support is available.
@JC-1 what was the outcome after all this anyway?
Also your location under your name is listed as NZ but you've stated your actually in Australia right?
It is the bike overall, the Gen3 Rail 9.8XT is a great buy especially at that price! I may also be a bit biased though. 2300km on mine and its been faultless, rides everything so well
You'll be fine on a 625wh battery. Your right 750 would be a bit overkill BUT resale is better and if you ever went on a longer ride its more than beneficial. You can also ride in higher power modes for longer of course.
The spec on the 9.7 Gen2 and 9.7 Gen4 are very similar, main differences...
Forgive the questions but better to get a wee bit of understanding..
Weight?
Physical fitness (out of 10, 10 being athlete)
What sort of distance will your usual riding be?
How much elevation in the above riding?
