If you don't know, the Bossnut is a full suspension £1000-ish mountain bike that has been winning awards over the last couple of years. Uses lots of well known parts and is famous for being well built and robust. I enquired about the suitability of electrifying it - here's the response they made back to customer services, who forwarded it on to me! I can kind of see why they want to do it, but there’s so much think about in the way of technical and regulations to be road safe. Cheap conversion kits are available, they’re on Ebay for anywhere around £800 but would definitely not recommend attempting to convert a Bossnut with any sort of motor or engine as none of the bike would have been designed, spec’ed or tested to take any part of an E-system. Bearings, pivots, suspension, tyres, brakes and frame tubing all has to be changed and specifically adapted to create to take the extra torque, speed and power put through it. Then there’s the warranty side, once this new system is bolted on the customer would no longer be covered by any warranty as the Bossnut has not been designed for E-system usage. To get an idea what sort of thing they could be looking at for the end product have a look in this link for Haibike, then once you’re sat down have a look at the prices. The reason the prices are so high is to do with the Bosch system motor alone is over £1,000, then add the battery at £540, then the controller, torque and speed sensors, cables, specific design of the frame, then on top of all that is all the regular gears, forks, wheels type of bike stuff. I urge you to have a look through the full range! https://www.e-bikeshop.co.uk/haibike-electric-bikes If the customer is looking for an E-bike, ours came out on Friday. It’s called the Kinetic, hardtail with front suspension, Deore 10sp drivetrain and only available in 6 of the stores (Stockport, Stockton, Milton Keynes, Cardiff, Swindon and Basingstoke), not on the web. There’s only 50 in this model.
