Haibike show no sign of slowing down in their quest for the best eMTBs possible. As the rest of the mountain bike industry scramble to catch up, the all-new xDuro (Bosch-powered) and sDuro (Yamaha-powered) line-ups jump ahead with the latest cutting-edge frame designs, drives, and components.
The Haibike sDuro AllMtn SL 27.5 is the entry-level electric bike for all types of terrain, be it mountain, trail, or free riding. The AllMtn range goes from SL to RC, RX, PRO and PLUS (wider 3" tyres), with the PRO costing nearly two thousand pounds more than this SL). Versatility is the name of the game here, and with 150mm of travel in those Suntour Aion RLR front forks, this is bound to be one of the big sellers for 2016.
Elsewhere, the AllMtn SL has a single chainring for it’s 10 Speed Shimano gear set (the other models in the AllMtn range have two chainrings, effectively giving you twenty gears).
Tektro Auriga disc brakes are front and rear with larger 180 / 203mm rotors for increased stopping power.
The 27.5" wheels feature the award-winning Schwalbe Nobby Nic rubbers, formed with dual compound grip so they roll fast but maintain grip in the corners.
In regards to the frame, the sDuro is very similar to the xDuro set-up, which we’ll talk about in more detail on the next bike, but rest assured the custom hydroforming and Gravity-Casting are better than ever.
Something the sDuro has that the xDuro doesn’t is automatic suspension control (e:i shock), adapting the rear suspension’s damper within a tenth of a second, under any conditions
Although the xDuro range is definitely the ‘big brother’ (Haibike’s own words) of the Haibike range, Yamaha were the first company to produce drive units for pedelecs way back in 1993. Their latest drive unit delivers 80Nm of torque (280% assistance), has zero cadence support (meaning you get assistance immediately, even on an uphill), and, although I couldn’t say with 100% certainty, seems to be silent. It was only after riding the bike that I realised I hadn’t heard the motor once.
The lithium-ion battery remains at last year’s 400Wh (2.9kg) capacity, but Yamaha have added a fourth assistance mode for 2016 - ECO+. Now the quoted max range of the battery is ninety miles, up ten miles from 2015. The large and clear display remains the same, featuring all the major statistics like speed, distance, battery life and plenty more. The battery charger has been radically reduced in size.
Last year, there were six models in the sDuro range - for 2016, that figure has nearly tripled to fifteen! It’s a sign of the popularity of Yamaha, as in 2015 they became the second biggest supplier, whereas the year before they were fourth. This AllMtn SL is a great addition.
