Marin have an all-new e-bike out called the Rift Zone E. With 29" wheels and 140 mm travel at each end, Marin say it's designed to be a do-it-all electric trail bike, with an emphasis on fun. It's strongly based on the Rift Zone pedal bike, although the electric version has 10 mm more rear travel to smooth out the faster, rougher climbs and more frequent descents. It uses an alloy frame with Marin's tried-and-tested linkage single-pivot suspension system.
Marin Rift Zone E Details
• Wheel size: 29"
• Suspension travel: 140 mm f&r
• Shimano EP6 or EP801 drive system
• 504 - 630Wh removable battery
• 65º head angle, 77º seat angle
• Aluminum frame
• Price:$4499 to $6299 USD
• marinbikes.com There are three models: E, E1 & E2. All use Shimano motors, with the EP6 drive unit on the E and E1 builds, while the top-end E2 model upgrades to Shimano EP801. Both motors produce 85Nm of torque. The base model comes with a smaller 504 Wh battery but this can be upgraded to 630 Wh. The top two models also come with CushCore fitted as standard.
The geometry is very similar to the non-electric Rift Zone, with a 65-degree head angle and short (for an e-bike) 440 mm chainstays.
The suspension linkage is progressive throughout, with 24% progression overall. The anti-squat is claimed to sit at just over 100% at sag. That means it should pedal efficiently without slouching and resist bottoming out too often.
Here are the key specs and prices of the three new models.

| Welcome to the Marin Rift Zone E.
To celebrate the new bike, we asked pro rider and celebrity Matt Jones to help us film a commercial.
While he loved the bike, Matt’s patience ran thin with the production crew (we’ve since fired them).
Sorry for the seeds, Mr Matt.— Marin |
Would never buy another Shimano motor until they have this sort of support
Not bashing, just genuinely curious.
Still - there are riders aging out or with injuries / heart conditions who can still play the game w/ ebikes. Check out the Singletracks (USA) mtb podcast from Feb 14 w/ Lennard Zinn - he wrote "Haywire Heart" which goes in depth on endurance / super atheletes and research about heart conditions they've developed from pushing too hard vs. genetics - and how to stay athletic once you know this. it. Its not a snowflake book & he's helped keep tons of people in the game w/ ebikes that would otherwise just be sitting on their asses.
Point being - not all riders are you or me, but if ebikes keep us riding w/ our parents or injuried buddies - why the hell not? If you don't like ebikes - you don't have to ride them or bust on people who do for whatever reason...its not gonna make anyone say "you know, I really shouldn't ride one because some guy said things". They make a lot of sense for many riders - even just having fun. I don't see what the gate-keeping is all about...even kooks can be trained. Lighten up, its just bikes.
My ep8 had a sprag clutch failure at around 600mi.
Why wait?
Ebikes are not allowed in western NC or most east coast (are allowed at bike parks) so I see no need to buy now but Ive been clearing & maintaining trails for 33 yrs and an ebike would give me massive distance & tool carrying ability that I don't have now for maintenance alone. My local trails have a 2500 ft climb to the good stuff so today, I got a total of 7 total mins downhill for 2 hrs climbing - tripling that in the same time on an ebike would be hella more fun, but it's national forest: no ebikes. The more important concern isn't tires on the ground - it's the number of people flying through remote / pristine / wildlife habitat & creeks, and that's actually the big issue, not a riders weight.
I have no clue what yr trails are like but "fat riders who do no work" sounds like there's not actual evidence to support it. To be sure - I"ll be that 90-95% of the skinny riders around me do no work around Pisgah...there are 1000's of people who come here but I've never once seen anyone - no one - cleaning up trails in my area.
Worth noting that they are not user serviceable, and can have significantly decreased performance after even just one service.
for bosch and shimano the bearings are all replaceable but diffrent parts like sprokets and axles are never sold.
The only E bikes motors we get whit problems are the tuned engines.
So what is the problem you referring to?
These motors should be able to be maintained by the user. Where are we in that Right to Repair movement?
Come on shimano, you can do a lot better than this!
There are too many factors involved to just say ebikes or more laps causes more damage - soil / geology type, steepness / slope, direction (N/S/E/W), weather, hot/cold ground level extremes, maintenance intervals - number of riders. In Pisgah Nat'l Forest, ebikes are not legal and there are 100's of riders per day on the main trails. Those trails have some places were 8-10 ft of soils have washed out massive gullies even decades ago from regular bikes. Today better design / runouts / erosion controls / rebuilds have helped fix that so matters less how many tires pass over them. My local goto trails 30 miles away gets 1/100th or less the usage of Pisgah proper - zero club maintenance have many rocky sections that are basically devastated steep hell-runs on south / southwest slopes but virtually none on even steepness north/northwest slopes due to soils / geology / aspect. None of this would really even matter in an area with heavy use that is more rolling or XC terrain (I think).
Just saying - its highly variable, lots of factors, and my two examples of heavy damage (among 100s around here) are fully without ebikes so to just say ebikes damage trails or 'fat riders who don't work" seems inaccurate (imo).
Right now I don't know.
Rise is good in that once its run out of power you can still ride it and its not a tank
While there are plenty rough & raw / rocky zones on local trails, that's maybe 1% or less of most of the trails vs. steepness & dirt and honestly it just seems most of the bigger travel is better when there are bigger jumlines & dropoffs, most of which is not in the enduro scene around here (most being national forest and a few bike parks now). Most of the guys (who race, I don't) who made the switch pretty much used to all ride bigass enduros until they tested out the smaller rigs once that geometry got amazing, and their times shot right up. Just sayin'... I think the assumption that bigger travel = wins is now outdated with newer geo on smaller bikes
Come and ride where I do on your hardtails and 120mm bikes and you will not enjoy it (or maybe you will, but funnily enough nobody here does it). Hence, this is not enough travel *for me*, and so this bike lost me at 140mm. If you ride in your local woods and don't want more travel cool, but in no way does that undermine what anyone else wants/needs.
As for "needing" an ebike (or any bike for that matter), "need" is an entirely subjective term.
Ebikes are for whatever you want to use them for. Plenty of them being ridden by decent riders all over the place, from trail centres to bike parks.
But hey this is PB, gotta gatekeep right?

This specs on a 5500 euro bike in 2023 ? OMFG this is laughable to death.
