Oxygen Emate City

At £1,089 from The Electric Motor Shop, this bike looks impressive.  Will take a heavy rider (20stones).Certainly worth researching. Here is the description and specs given on The Electric Motor Shop’s website:

The best thing when a bicycle goes electric is the thrill of riding it as the experience would be completely different after having to ride the bike manually all these years. Oxygen E-mate City is a popular name in the electric bike section and comes in various price ranges. Oxygen Emate City – 37V 15.5Ah uses a 37V 15.5Ah battery of Lithium and ranges up to 70 miles. It has lighting system fully LED and along with Bengal disk brakes, and and Suntour suspension forks and very comfortable Velo Plush saddle. With cool designs and its availability in various colors makes it an attractive proposition.

The motors used are very advanced and use a permanent magnet brushless construction along with a gear-reducer system. The brushless design ensures higher efficiency and low maintenance along with being water-proof and light weight. The lithium polymer battery present in Oxygen Emate City – 37V 15.5Ah is very well designed to be light weight and has very high power density which allows the use of around 900 cycles. The alloy wheels, disc brakes and heavy duty carriers in the rear make it a perfect vehicle for riding.

The OXY drive LCD screen acts as an interface to display the various functions performed in the cycle like the average speed and the battery usage. For providing better riding experience the various angles and positions have been taken into considerations following the principles of ergonomics. The frame of the cycle allows three types of riding positions and is certain to prevent back pain in riders. Cycling is considered the best exercise for the body and these electric bikes will go a long way in providing optimum exercise to the riders who prefer taking a break while cycling.

Review from 50cycles:

“Thank you so much for the bike it’s AMAZING, I totally love it. It is a great bike really lovely to ride and as you said perfect for the Worthy Farm terrain.”
Lucy, Green Initiatives Coordinator at the Glastonbury Festival

The Oxygen E-mate City combines all the necessary features of the city bike such as comfort, safety, reliability and swift movement. This is perfect choice for those who want to feel the freedom of cycling with less (or even none) of the effort. The 2012 Oxygen comes with a new lightweight Lithium polymer battery pack that boasts an enormous 37V 15Ah capacity, LCD display unit, new Oxydrive motor and 7-speed Shimano gears. Suitable for most riders between 5’7″ and 6’4″ (167cm – 195cm) in height.

:: 2012 Oxygen Emate Ride report
On first appearances it’s much the same as the 2011 version with the same trademark frame shape, mudguards, handlebars, etc but on closer inspection the motor is larger than on the previous model and branded ‘Oxydrive’, which is the stronger motor Oxygen are also using in their kits. I believe it’s rated at 350W but limited in the UK down to 250W, but able to peak much higher for pulling away and hill-climbing. How high is given away by the new LCD display on the handlebars which showed peaks up to about 568 Watts, which is a useful amount of power on an ebike.

The throttle works as expected but the pedelec system feels much improved – smoother and more positive, perhaps something to do with having more power available. The level of power assistance can be adjusted between 4 levels – eco, normal, speed and power. The gear shifter is now a twist-grip rather than a fiddly trigger operated one that used to sit next to the throttle.

I found the ride quality was excellent, somehow improving on the original. For example, I was able to ride for hundreds of yards with my hands off the handlebars as the bike was stable. I don’t know how he’s designed that into it, but it was notable.

All in all, I can happily recommend the new version. Improved power, performance and ride quality.
