An entry-level Haibike still gets you 80 newtons of smooth Yamaha torque (280% assistance, to me and you), 100mm of travel in the front suspension fork (with instant lockout), for instant switch from trail to tarmac, and a full Shimano Deore 10-speed drivetrain.
Yamaha sDuro motors offer four assistance levels, the 'Eco+', 'Eco', 'Standard' & 'High'. Start pedalling and that power curve will start to rise, nice and smooth, and supremely satisfying. Electric bikes need to be experienced, and you can’t get a noticeably better performer than the Yamaha. The new minimum for 2016 electric bikes, there’s a 400Wh battery on-board, which Yamaha claim can assist you up to 90 miles on the new Eco+ assistance mode.
The sDuro HardSeven SL comes on a matt black and white hydroformed frame, with cyan highlights sparingly used. The new 27.5" (650B) wheel size slams together the best bits of 26 and 29, supplying plenty of manoeuvrability and coverage. And both front and back wheels are quick-release, just in case you were to get a puncture (as if…)
Schwalbe Rapid Rob tyres have a good reputation for roll and summer trails, and the Kevlar lining means they’re pretty puncture-resistant too.
As with all Haibike suspension systems, the Suntour 100mm fork is fully air-adjustable, so the rider’s weight can be integrated into the overall set-up. It’s a heavy but firm fork, which is what you need for the added weight an electric bike brings.
Lastly, front and rear Tektro hydraulic disc brakes with larger 180mm rotors give very good deceleration.
If you want to get into the Haibike game, the sDuro HardSeven SL is an excellent place to start.
