Haibike AllMTN 3.5 Review – An E-Bike that eats up the trails

The NEW ‘All Mountain’ 3.5 from Haibike is a little bit of a beast. Having come from the non e-bike world, we were shocked at the assist this bike can give with its new Bosch Gen 4 motor. Both myself and Sam are now running a 3.5 along side our unassisted mountain bikes. We have entered a whole new world where-by we both could not recommend a pedal assisted bike more. A lot may say this is cheating, and I would urge you to read our previous article which goes into more detail about this here.

So how much power?

With its all new Bosch Gen 4 motor (Bosch Performance CX), the bike has 75Nm. Put together with the 625Wh battery and you have yourself a bike which is looking for a challenge as you venture further afield.  You can purchase an optional range extender to increase the already large capacity by a further 500Wh. This mounts onto the frame, above the standard integrated ‘PowerTube’ battery. That being said, the batteries themselves are not light by any means. We were recently discussing how the benefit of an additional PowerTube battery could be great on those days out. Most people do not have the luxury of a power setup while out on the trails. Wouldn’t it be great to go out and drain the battery of all its juice, get back to the car park for lunch, and then install a fresh battery for even more fun.

There are 4 modes on this particular model (other manufacturers do vary). You have Eco, Tour, EMTB and Turbo all of which offer different levels of assist up to 340%. A recent trip to Surrey Hills saw us both push the bikes to what we thought was the limit. We found a very steep, loamy and overgrown off piste trail. We selected Turbo and proceeded to climb. Bearing in mind the bike alone weighs close to 25 kilos, with the additional weight of a person and gear. To our amazement, the bikes clawed their way up to the top. These bikes are impressive pieces of kit!

Geometry of the Haibike XDURO AllMtn

The 3.5 is a complete re-design, with a 29″ up front and the standard 27.5″ on the rear. This bike is running a mullet setup (Always makes me smile). Straight away when you descend trails on this bike you can see how the 29″ enables to bike to roll over things much easier than a full 27.5″. Personally speaking, I have only ever ridden a full 29’er once, and it felt foreign. However the mullet set-up is middle ground and a choice that has proved to pay off considerably. For those rooted sections of trail, this bike just eats up the terrain and feels solid, stable and strong!

So with all this weight you need stopping force…

A 25 kilo bike loaded with one full human and gear makes for a pretty weighty lump. When smashing it down a trail to the bottom, you want to know and be reassured that you can stop on demand. That is where the Magura MT7 4 piston brakes come into their own, you can feel the power of them compared to some standard 2 piston brakes. We have been riding for a good time on these bikes now, and have given them a chance to bed in properly and be tested to their full capacity. Not yet have we had any issues, if anything, they loosened the disk bolts. Some loctite and torque and this problems was soon rectified. Would highly recommend these brakes to anyone who has had stopping power issues, and we cannot wait to test them in the real mountain environment once lock down eases #COVID19

Magura MT7 4 Piston Brakes


Haibike has paved the way for other bike manufacturers to create their own take on what an E-Bike should be. With the likes of Specialized, Lapierre, Santa Cruz, Trek and Scott all now having a range of E-Bikes to choose from. We have watched Haibike from the near beginning and with this All Mountain 3.5, it has opened up a world of opportunities. We may have only ridden once a week on our normal bikes and not really travelled too far. What this E-Bike has meant now, is that I am doing close to 2 or 3 rides a week and exploring local trails and countryside. Now when we go to a park such as Surrey Hills, we can now do 3 or 4 times as much, which adds up to smiles and fun. The 3.5 is a great bike and highly recommended (If you can get one during lockdown haha). There seems to have been a spike in mountain bike sales and more specifically E-Bikes.
