E*POWAH Elite World Champion
Figured I'd start this thread because one doesn't exist.
The above is my own and should be treated as an example of this 200mm Travel front and rear emtb. Naturally, better components can be used.
I've opted to build my own from a frame (not frameset). But at one point, you could buy these ebikes complete. Reserved more for the German market.
Powered by the Bosch Gen4 motor and a 630wh battery, I don't mind admitting that this won't be easy to build for a lot of you. I was fortunate enough to buy a brand new motor (with legit 2 year warranty) here in the UK. Special Thanks to True North Cycle Hub for the hook up. Much appreciated
Initially built up in it's 180/185mm travel configuration to see whether it could work/deviate from it's default downhill form
And then built up in it's 200/200mm Travel Downhill form. Personally I feel that this is the only form the bike should take, as I did find the bb height a bit low using a 180mm fork.
And for good reason, as clearly this ebike requires an axle to crown length of atleast 600mm. And I believe only a Zeb 29er set at 190mm travel is the only single crown fork which would meet the required axle to crown length.
The above geometry chart is accurate. The default headtube angle is 65° with a 75° seat tube angle and my XL having a reach of roughly 504 (507mm I'm getting) with a chainstay length of 480mm.
Whilst most will comment on the "conservative geometry", please bear in mind that I am no stranger to amending geometry on diy ebikes. So slackening the front won't be that difficult.
The bike can easily be mulleted, considering the offset requirements on the geometry chart stating 51mm which was reserved for 29er forks years ago.
And Offset Bushings can easily be used for the standard eyelet bushing 230x65 shock upper
and low. 8x22 for lower and 8x23 for upper.
Speaking of, you've probably noticed the different mounts for the shock. It isnt a geo adjust. Moreso, the bike has an adjustable leverage rate depending on the lower shock mount position.
Truth be told, I haven't played around with this too extensively. But my plan will be to experiment with a coil shock in due course.
But the general gist I've got from the factory is:-
•In the forward position, it's more plush.
•In the rear position, it's more firm.
Sadly, I'm unable to share any details concerning the suspension side of things (especially the leverage rate percentage per each position. Because the factory haven't provided me with that information. So it took a while just to set the sag which I'm fairly confident is around 30-35%.
Naturally, if I'm furnished with authentic details about suspension, I will share and update the thread.
I won't bother going over the entire spec and components on my E-cross, as I do appreciate that it's not using the newest & latest and greatest of components.
Including the pre-2023 Bosch Gen4 system. Made evidently clear due to using the Bosch Purion display and the 630wh Horizontal battery.
The frame construction has been pleasantly surprising. Using T1000 Toray carbon for both the seatstay and chainstay with dedicated intube cable routing.
And T800 Toray carbon for the main triangle with the cables being nestled on the undercarriage of the downtube, secured by a metal plate preventing excessive cable rattle.
7075 alloy rocker link which doesn't use a seatstay bridge.
With plenty of room for wide volume tyres (27.5).
I haven't tried a 29er rear wheel yet. But supposedly, you can run up to a 29x2.35 tyre....supposedly!!
No udh. Although, I swear I've seen the derailleur hanger design on other bikes/ebikes.
Proprietary chainstay protector which is included.
Headtube cable routing....thank God!!
...seriously. could you imagine headset cable routing with a dual crown fork. Especially if the headtube length is over 130mm.
And an overall weight of 25.46kg for this XL set up tubeless with pedals and a bottle cage. Again, components will change. So the weight will change.
No alloy models. Only Carbon.
And to make it clear, this IS NOT Dengfu, Lightcarbon, Shenzhen Zhaosheng,
...or Mondraker.
I'll update as and when I can but feel free to ask any questions. My ride impressions of the bike will follow soon
