With 100mm of travel, this hardtail electric bike is the entry level model within the Haibike sDuro range. The HardSeven 2015 eBike is built on more entry level components without compromising quality. It is designed for the eMTB'er who wishes to take on some of the local trails. It is suitable for XC / Trail use. Can also be used as a clutter free commuting bike.
To sum up, it's fantastic! I came to the conclusion that it's possibly the best purchase I've ever made. Value for money spot on, quality spot on, service spot on. Just buy one! Whatever you want it to do it will exceed your expectations and look mighty fine in the process. If a smile is worth a pound It's already paid for it's self. Happy riding guys!..
The brand new Haibike HardSeven SL 2015 eBike is an exciting one for us, it offers an affordable way into the crank drive electric bike world.
This eMTB features the the new revolutionary 27.5" (650B) wheel size which takes all the benefits of both 26" & 29" and squeezes them into the ultimate hardtail.
Haibike have equipped this model with a Shimano 9 speed gear system, which operates on trigger shifters.
The HardSeven SL features a Suntour 100mm front suspension fork with lockout so the riders energy can be conserved whilst climbing or on less bumpy terrain.
This fork is air adjustable and can be pressurised for the riders exact weight. We see the Tektro hydraulic disc brakes front and rear with larger 180mm rotors for increased stopping power. The 27.5" wheels are made up of XLC disc hubs which are quick release front and rear, these are laced onto Rodi disc specific alloy double wall rims and Sapim double butted spokes.
Although the entry level model Haibike have managed to squeeze a decent set of Schwalbe Rapid Rob tyres into the equation.
These tyres offer decent off road grip but don't pick up too much resistance on tarmac or hard pack terrain.
All in all the new Haibike HardSeven 2015 model is certainly a eBike not to be reckoned with in terms of its affordable price ticket and the components used.
A German built bike with the Yamaha crank drive motor, all for under £2K? You decide!
Haibike sDuro range?
The new Haibike sDuro range is focused on the younger generation. With the age range of people using eBikes getting younger and younger the sDuro electric bikes are all equipped with the Yamaha eBike system offering a more affordable system to younger people.
The prices, styling & design reflect this and the bikes start at a lower point and only go up so far. The xDuro range then crosses over and takes the component level further for more advanced riders. The sDuro range was developed for riders in the age range of 20-30 to offer a new level of eBikes to the next eGeneration.
The new Haibike sDuro HardSeven SL is powered by the latest Yamaha electric bike system. Haibike has partnered with Yamaha to bring a brand new line of sDuro eBikes, this powerful 250w motor offers up to 280% assistance and peaks at 80Nm of torque.
The power curve comes in early and is responsive as soon as you touch the pedals. The assistance is set in 3 levels - 'Eco', 'Standard' & 'High'. This allows the user to fine tune the amount of assistance required during the ride offering complete flexibility and control.
You can read the full review of the Yamaha eBike system on our blog pages here.
The Yamaha system uses a 400Wh battery with an assisted range of up to 80 miles. The Haibike sDuro Hard Seven SL 2015 eBike is offered with the largest 400Wh battery to give a full days ride time. It can be quickly recharged in a matter of hours and the new LCD display shows not just how much capacity the battery holds but also the predicted range in assisted miles.
