Boadman ADV 8.9E – The best value electric Road – Adventure – Gravel Bike available?
Boardman have been producing some excellent bikes over the last few years, and I always had a feeling that when they entered the ebike arena they would carry on that trend.
Having already ridden their excellent electric hybrid bike, I was keen to try out the Boardman ADV 8.9e adventure / gravel / road bike. This ebike uses the same Fazua Evation motor as it’s flat bar sibling. Read my full review below for more details.
Electric road bikes have seen a massive expansion in popularity over the last couple of years This is thanks in part to the development of lightweight ebike motor drive systems like the Fazua Evation and Mahle X35 ebikemotion.
The early mid-drive and hub motor systems commonly found on electric bikes were quite heavy, as were the lithium batteries that accompanied them. Thanks to recent advances in both ebike motor and lithium battery technology – motors and batteries are now much lighter, and can be better integrated into electric bike design.
To the casual observer, the Boardman ADV 8.9e looks just like a regular road bike. The only giveaway is the slightly larger downtube, which accommodates the 252Wh battery and motor drive system.
As I stated in my review of the Boardman electric hybrid bike, the great thing about the Fazua system, is it can be easily removed. Meaning you can have an ebike for the daily commute and a regular road bike for weekend riding.
The German-made Fazua Evation has revolutionised the electric bike motor. The Fazua Evation was released at the end of 2018 and was designed specifically with the electric road bike in mind.
The Fazua motor gearbox in neatly integrated into the bikes bottom bracket, and you insert the motor drive unit into the gearbox.
The small 250 watt-hour battery connects to the top of the drive unit and can be easily replaced – a spare battery is available if more range is required.
The electric assist system is controlled by a remote control handlebar-mounted keypad. There are 10 LEDs showing the battery level. These change colour depending on what pedal assist mode you are in. White is zero, green is low, blue medium and purple is maximum assist.
The Fazua motor is best-suited to the rider who only requires e-assist on occasion – for climbing hills and to provide some extra help for longer rides. As the battery is of quite a low energy capacity, it would be ideal for commutes of up to around 30 miles (with the assist on constantly).
The total weight of the Fazua system including the battery pack is just 4.6kg. If you fancy riding without the extra weight of the electric motor and battery, you can easily remove it, fit the (optional) alloy cover and away you go!
It should be noted that you don’t loose the whole 4.6kg when you remove the motor and battery, as the gearbox that is integrated into the bottom bracket weighs 1kg, but you still loose 3.6kg – which makes a lot of difference.
The quoted maximum torque figure of 60Nm feels about right. The performance feels similar to the Bosch CX motor in tour mode. When the assist is switched off or the maximum assisted speed of 15.5mph is reached, the motor de-couples from the gearbox, and there is no extra pedalling resistance – if feels just like riding a normal bike.
I rode this bike for around 8-9 miles of hilly Cornish countryside, and when the motor was off, I didn’t really notice the extra weight, in fact I could quite happily ride the ADV 8.9e with the motor switched off for miles and it wouldn’t bother me.
I also rode the ADV for a couple of miles with the motor removed, and it felt a lot lighter and zippier than my vintage Dawes Galaxy touring bike
The pedal assist on the Boardman ADV 8.9e is so smooth and subtle, it feels like you have strong wind behind you. I had my Wahoo Elemnt Bolt bike computer fitted, and I was going up hill considerably faster than usual, but with half the effort.
Fazua Rider App
The Fazua rider app is an excellent accompaniment – It has the following features:
- GPS navigation, tracking and trip information
- Motor power, remaining battery capacity, distance to empty, etc.
- Speedometer, cadence, rider power, rider torque, etc.
- Technical overview and battery charge information
- Support functions, incl. direct access to Fazua Service
- Ability to share rides with friends
- Summaries and analysis of the data post-ride
The app is compatible with Andriod and Apple IOS, and it really does provide some useful information, plus some of the more technical stuff like rider power, cadence and torque. You can also track ride data and share with friends.
The addition of GPS navigation is a great feature. But remember, you will need to get a suitable smartphone holder for your device – the Quad Lock is probably the best phone holder available for bikes.
Conclusion of the Fazua Evation system
I prefer the Fazua Evation to the Mahle X35 ebikemotion system found on the Orbea Gain and other electric road bikes. I do like the X35 system, but having a motor and battery that can be removed in seconds means you can enjoy the best of both worlds. You no longer need an electric bike for commuting and a regular bike for weekend rides – you can have both in one!
The small 36v 7ah (250Wh) battery is lightweight and easy to plug directly into the drive unit. The range of the battery will really depend on the rider, and how often the e-assist is used.
As with the Hybrid version, there is not reason, why you couldn’t squeeze 100 miles out of a single charge if you only used the assist for 30% of the ride.
For a daily commute to work, and using varying assist levels, I would say a range of between 30-40 miles should be possible.
The Boardman ADV 8.9e uses the excellent SRAM Apex 1 x 11 drivetrain. Upfront There is an FSA-CK746 crankset with an FSA 44t chainring and a wide range 11-42 cassette and the rear.
This groupset is designed specifically for gravel / adventure bikes and will ensure a decent range of gears for climbing steeper hills. The package is finished off with a high quality KMCE11 ebike specific chain.
The SRAM Apex hydraulic disc brakes combined with 160mm rotors provide confident braking, no matter what surface you are riding on. I felt these brakes did the job perfectly.
Wheels and Tyres
The wheels are Boardman branded tough double-walled rims with thru-axles front and rear. There are 28 spokes on the front and 32 on the rear.
The tyres are Schwalbe G-One Speed, 700c x 38mm gravel tyres, which will offer a good level of puncture protection and are excellent on a multitude of surfaces
The finishing kit is all, good quality Boardman branded components, with flared drop bars and a Fizik Tundra saddle.

Frame and Forks
The Boardman smooth weld alloy frame is just beautiful, with internal routing and a relaxed geometry, this really is a nice frame. The Fazua motor system neatly integrates into the oversized down tube, making the bike look like a regular bicycle.
High quality carbon forks, help dampen road buzz, and thru axle forks keep things stiff up front. The headset is a high quality FSA No. 42 ACB.
Who is the Boardman ADV 8.9e aimed at?
I would say the Boardman ADV 8.9e is aimed at road cyclists who are after a bit of assistance once in a while. A bike like this is really versatile, and can be used on road or gravel tracks.
At just under £2500 it may not suit everyone’s budget. But it is the cheapest Fazua-powered electric road bike currently available.
There are also provisions for fitting mudguards and a pannier rack making it an ideal commuter or touring bike.
The Fazua Evation ebike system is fairly recent, I haven’t been able to find to much information about long-term reliability. I think it’s safe to say for the moment, that this drive system is going to be fairly reliable. I have already ridden quite a few Fazua-powered ebikes and they all work flawlessly.
As with all their bikes, Halfords and Cycle Republic provide a 2 year warranty on all the electric bikes they sell, so customers needn’t worry. Plus, if the motor ever did develop an electrical fault, you can remove it and use it as a normal bike. Something you would not be able to do with a Bosch-powered bike.
I prefer riding road bikes, so the Boardman ADV 8.9e was right up my street! Having ridden several different makes a models of ebike using the Fazua system (including the Carbon fibre Cube C:62) I have to say, the Boardman is definitely the best value by a long stretch.
You will struggle to find any other e-road bikes using this system for much under £3000.
Just like the hybrid version, this bike won’t be for everyone. Some say the motor doesn’t give enough assist. Personally, I felt it produced ample help, but I am in reasonable shape and ride between 50-100 miles per week on a regular road bike.
If you are looking for an electric bike to give you more of a kick, it may be worth looking at an ebike with the Bosch CX, Brose, Shimano Steps or Yamaha Sync drive motors. These all produce substantially more torque, and will definitely perform better on hill climbs and have longer battery ranges.
If you’re looking for a versatile and practical electric road bike that can be used as a normal bike from time to time, the Boardman ADV 8.9e would be an excellent choice.
