Shimano MT200 Brake Lever and Hydraulic Disc Brake Callipers Shimano 2 piston hydraulic disc brake callipers and levers that have been specifically designed for off-road riding, providing braking power tuned for entry-level riders and an adjustable lever reach designed for all sizes of hands.

Kenda 29”x2.20” Tyres Kenda’s 29”x2.20” tyres offer a massive amount of grip and control on all terrains, both on the straights and in the turns. Cornering knobs are positioned far down the tyre wall, providing you with the reassurance needed to really test the limits. The large 29” tyre also makes riding over obstacles easier, providing a smoother & easier ride.

Gear Sensor and Inline Gear Cable Sensor This unique system developed and made in the Czech Republic is based on intelligent gear sensor technology fixed on the shifting cable, which cuts off the motor drive when the rider activates gear shifting. This brand-new technical solution eliminates user-unfriendly and noisy rear derailleur shifting which is caused by chain overstraining. The Gear Sensor system in combination with the front derailleur and the internal gear hubs allows perfect shifting performance. The inline gear cable sensor works to keep in sync with the electrical assistance being provided by the drive unit and the mechanical gear that is being selected by the rider. This means that the gear changing process will work as smoothly as possible, whilst putting less stress on the mechanical gear shifting components, thus prolonging drivetrain life.

I found the bike to be excellent. Thanks to Eco Bikes for their advice and time.

David Ward
Great mid drive bike at good price

Had a cheap ebike from Amazon for the past three years and have been looking for an upgrade. The Avaris Odysey seemed like a good choice, I never thought I'd get a mid drive at this price. Not only does it have a great motor but the battery is massive. On my first charge I topped it up to 94 percent and managed 68 miles and still had 26 percent left so I reckon I could get very nearly 100 miles. I thought the seat looked quite uncomfortable but have been pleasantly surprised. The one negative would be the weight, it is advertised as a lightweight bike, at 33 kilos it is quite heavy and I won't be carrying it too far.
All in all this is a great bike and deserves the 5 star rating.

John Truswell
Easy to order and good communication

My first Electric Bike but I have hired and borrowed a few in recent years . I had been researching the market for some time and the Avaris Odysey looked to have a good specification at a good price . The order process was easy and safely delivered by Parcelforce. it was easy to add the pedals and adjust the handlebar angle. The written instructions for the bike could use more detail. I bought a spare battery due to the hundreds of battery variants available and the knowledge they dont last forever . The spare battery seemed good value at £150 . I couldn't work out how to remove the battery but was given e mail support and the offer of a video call by Avaris . The bike tube where the battery is located on the bike must have a spring pin which retains the battery when the lock is undone to stop the battery falling from the cross tube . It needed more force to remove the battery and overcome the spring pin than I was expecting and an e mail gave me guidance. I found a video on You Tube of the battery replacement on the road bike version which isnt the same, as the battery is removed upwards not down . . I also needed to find and download the manual for the bike computer Bafang DPC18 , which I think should have been supplied with the bike in paper format but easy enough to find on line . The bike works well and has lots of power . I havent had a chance to check the full range yet but it should have plenty

Excellent bike just what l need after a knee replacement at 68.

Decent bike

Tim Chambers
Happy customer.

Really happy with my new Odyssey mountain bike. Easy to get road ready and first ride was great. Went for what I would have considered a long ride on my old bike and found it very much more achievable using only level 1 assistance. Only required higher level of assistance on a very steep hill that I used to struggle with. It was a big purchase that I thought very seriously about but absolutely no regrets. Very high spec for the money. Could have paid a lot more if I had not found this bike.The free 10 days insurance was a great idea that gives you time to shop around without doing anything in a rush. Cant see me riding my old bike again!

Avaris Odysey Mid Drive Electric Mountain

The bike is beautiful, smooth ride and very robust. Less impressed with the aftercare and instructions for assembling the bike, but that is a small matter. Good company that have looked after me buying a massive life changing purchase now I am free from the tyranny of the car. Thanks guys

David Buckby

Good communication pleased with the bike

Recently used the Avaris mountain bike to go on rides with my husband, who is a keen cyclist and has a ridiculously expensive bike. I thought I’d start with electric and with a mid-range model in the Avaris. Must say I have been very impressed; the assist takes away all parts of cycling that aren’t fun i.e. hills and getting too tired and also means I can go much further and ride for much longer whilst likely doing more exercise. Been heading to the Peak District often. Brilliant bike, 5 stars!

Richard H

At 63 years old, I thought it was about time to get an eBike since I’m no longer a whipper snapper, but still love cycling. Did a lot of research and decided on the Avaris. Blown away with the capabilities of this bike, I can now travel much further than I was doing before without anything being too taxing or getting to a destination and thinking I’m too knackered to get back. Also been heading out with my 26-year-old son who I can now more than keep up with to the point he’s now decided to go electric!
