Wow I just watched the review. The bike wouldn't climb the same hill as some of the cheaper models...is it just me or was this devastating for this high priced bike?

It definitely has curb appeal.

Was that the sduro review? The geometry and build of the bike being a downhill bike, and court's riding style could be contributing factors. Court has indicated the Yamaha motor cuts out above 90rpm and isn't suited for high cadence riders. He also has bad knees that prevent him from putting more torque into his pedaling, which could also contribute. I would put too much stock into a single ride, and it does sound like that portion of the new review ride is quite steep. One misstep on hearing can end a difficult climb pretty quickly!

He climbed the same hill with the an S duro and a less expensive Bosch bike. He made it up easily. He did talk about a different chainring...isn't the point of this bike to take you up aggressive hills so you can 'Bomb' down...????

@Court any thoughts?

The issue was not the chainring, but the rear cassette. The XDuro Downhill Pro has a 11-36 tooth 10-speed Shimano Saint rear cassette while the XDuro Fullife RX had an 11-42 tooth 11 speed Shimano Deore XT rear cassette. The larger rear sprocket gives 17% lower gearing on the XDuro Fulllife RX. Given that both bikes have an 18 tooth drive sprocket and the same Bosch Gen 3 drive motor, the Fullife RX has more mechanical advantage for climbing. Of course, a rider who plans to bomb downhills in a $9,000 bike is presumably a "stronger" rider (grin!). A change to an 11 speed XT or XTR deraileur and shifter would be required to get the lower gearing on the XDuro Downhill Pro.

Maybe I am old and just don't understand...
1. This is a downhill bike
2. To ride downhill you have to get uphill
3. I would think the gearing would be extra efficient for climbing on a DH bike
4. The same rider had to push the bad boy Haibike up the hill he rode up on two less expensive Haibike modelso_O:confused::D:p

I not trying to be difficult just seemed like a miss for such an extreme bike.

Oh well I will leave it there. I am a flat lander anyway.

Well, Court's videos give excellent overview of the bike but there is just no way one could determine it's capabilities from any video review (either court or anyone else) unless you put a power meter, heart rate monitor, oxygen sensors and create a baseline for comparison.

My guess would be a combination of the gearing that Douglas pointed out, and the geometry of the bike. The body position is very rear oriented so it would be more difficult to put power into your pedal strokes.

I don't know why Shimano does not provide an 11 speed 11-42T option in their Shimano Saint "downhill" groupset, but I would guess it is because downhill riders want a quick shifting mech that has a shorter cage, so the Saint derailleur cannot handle the 31 tooth cassette spread that the Deore XT can. By the way, I am old too and am used to riding a 1971 Campagnolo Nuovo Record road bike that ia limited to 42-52 chainrings in front and 13-26 5-speed freewheel in the rear. I have since "upgraded" to vintage first-gen Campagnolo Rallye derailleur and run 42-52 front and 14-32 6-speed in the rear. Woo-Hoo!

Electric downhill bikes are still just for downhill. If you want to climb, don't get a downhill bike.

Downhill bikes have reinforced frames that add weight, and they also have double-crown forks that add even more weight. Some motor-less downhill bikes weigh 40lbs, which is nearly what an ebike weighs. The Haibike XDURO DWNHLL Pro weights 53 lbs, which is ~5lbs more than last year's FS RX. This weight penalty combined with the downhill-specific rear sprocket means that you won't be able to easily climb steep hills.

OK a little follow up:D
This review and topic is for a DH bike.

If I am going to purchase an electric DH bike...I would do so...for help climbing. Lol

This is a huge miss in my mind. This EBike should climb anything it is pointed at.

I consulted a couple of my boys running mates (avid MTB crew) and asked: if you were going to buy an electric DH bike (which none of them would)...why would you by E Assist. Common answer: "to help with climbing".

If I was a Haibke manager...I would have an immediate meeting with the engineering department and ask: why won't our, top of the line, bad boy E assisted, 9K, DH bike, CLIMB!

It shouldn't need any excuses.

Common this funny no matter what your perspective:p
