Haibike SDURO HardSeven 8.0 e-bike review

Feb 2019

The Haibike SDURO HardSeven 8.0 is an aluminium hardtail e-bike best suited to touring and tamer terrain. Built for comfort over the distance the e-mtb does what it says on the tin and is pretty good value too, but it’s not a trail shredder.

Haibike SDURO AllMtn 7.0 e-MTB review

Dec 2017 · Guy Kesteven

Potentially decent plus-tyred cruiser, but weight, handling and Yamaha motor limit current fun

Highs
  • Smooth, traction-friendly power and high maximum torque

Lows
  • Motor lacks initial bite, and torque/cadence-based assistance bandwidth is narrow

  • Integrated display is hard to read

  • Tall, short, high-standover ride position means it’s not naturally aggressive or tech-minded

Haibike SDURO HardNine 4.0 Review - Prices, Specs, Videos, Photos

Sep 2017

Price: $2599.00 | Model Year: 2017 One of the most affordable Haibikes in the line, available in four frame sizes, relatively lightweight, large 29er tires provide float and momentum at speed for cross country riding. Very capable mid-drive system (the same motor and battery as some higher-priced Haibike models), zero cadence assist feels responsive from starts and climbing. One of the most affordable Haibikes in the line, available in four frame sizes, relatively lightweight, large 29er tires provide float and momentum at speed for cross country riding.

Observations
  • One of the most affordable Haibikes in the line, available in four frame sizes, relatively lightweight, large 29er tires provide float and momentum at speed for cross country riding

  • Very capable mid-drive system (the same motor and battery as some higher-priced Haibike models), zero cadence assist feels responsive from starts and climbing

  • Powerful 180 mm hydraulic disc brakes for handling the increased weight, capable 100 mm suspension fork with compression adjust lockout, Shimano Acera 9-Speed derailleur

  • The charger is bulky and heavy but offers faster 4 Amp power flow, Fixed display offers fewer readouts but is actually very capable (battery percentage, range, etc.)

May 2017 · Christoph Bayer

Haibike’s product line is huge, its number of models is enormous! The Haibike SDURO AllMtn 7.0 is one of their biggest sellers – is this justified?
