At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean

Morgan Blue Bio Bike Cleaner is eco-friendly yet effective, shifting even chain grime and grease without harsh chemicals. Shame you can't buy refills, though – and it's expensive.
Bio Bike Cleaner comes in a 1L bottle with a separate spray nozzle. The nozzle is adjustable, so it's easy to direct without wasting loads as overspray. It's a bit disappointing not to see any kind of concentrate or bulk refill to encourage reuse of the plastic bottle, though.
Morgan Blue recommends rinsing the bike with water, spraying it, scrubbing with a 'chain brush and cleaning glove' and then leaving it before rinsing. Sticking to my usual tools – a tooth brush for the chain, a paint brush for the cassette and sponges for the rest – but otherwise following the instructions sees every part sparkling clean.
I've used the cleaner on my mountain bike, gravel bike and winter road bikes and been thoroughly impressed. It foams up nicely when brushed into the chain, and cuts through grease without too much scrubbing. No, it doesn't dissolve grease on contact like toxic alternatives, but it ultimately comes up just as clean with a scrub and there's no effect on the skin or strong smells.
You do need to leave it for a couple of minutes before rinsing, as the instructions say, though.
I overdid it on the first few uses – you don't need a huge amount. I've had well over a dozen washes out of the bottle. How long it lasts will ultimately depend on how dirty your bikes are.
There are an increasing number of environmentally-friendly options out there, though it's frustrating some – like this – are still so expensive. The Juice Lubes Dirt Juice Double Pack, for instance, includes a 1L bottle and a concentrate refill that gives you 12L total for only £16.99. This works out at about £1.42 per litre, and it's biodegradeable.
The price per litre comparison needs to be taken with a pinch of salt, though, as fluids vary in the amount you need, particularly to clean the chain. Morgan Blue's doesn't need much to shift chain grease and grime.
Morgan Blue Bio Bike Cleaner is very effective, even on clogged-up drivetrains, but it's expensive against the many alternatives. Without the option to buy a bulk refill or a concentrate, the 1L spray bottle doesn't represent great value – and will soon end up as yet more plastic recycling, if only because you've use the cleaner up quickly because it works so well.
Great green option that cleans very well, even on the drivetrain, but pricey and no refill options

Easy to use sprayer is adjustable to reduce over-use.
Performs really well, particularly on oily chains and cassettes.
It depends on how dirty the bike is, but I've had about a dozen washes out of the bottle. I think I could have got away with using less on the first couple of uses. You don't need a huge amount - the chain certainly doesn't need much to get a sparkle.
No effect on the skin.

A faultless cleaner, but pricey in comparison to others – and despite it being a bio product, there is no option to buy a refill or concentrate to reduce plastic waste. Overall though, it's good.

Emma’s first encounters with a road bike were in between swimming and running. Soon after competing for GB in the World Age Group Triathlon Championships in Edmonton in 2001 she saw the light and decided to focus on cycling.
After a couple of half decent UK road seasons racing for Leisure Lakes, she went out to Belgium to sample the racing there and spent two years with Lotto-Belisol Ladies team, racing alongside the likes of Sara Carrigan, Grace Verbeke, Rochelle Gilmore and Lizzie Deignan. Emma moved from Lotto-Belisol to Dutch team Redsun, then a new Belgian team of primarily developing riders, where there was less pressure, an opportunity to share her experience and help build a whole new team; a nice way to spend her final years of professional racing.
Since retiring Emma has returned to teaching. When not coercing kids to do maths, she is invariably out on two wheels. In addition to the daily commute, Emma still enjoys getting out on her road bike and having her legs ripped off on the local club rides and chain gangs. She has also developed an addiction to touring, with destinations including Iceland, Georgia and Albania, to mention just a few. There have also been rare sightings of Emma off-road on a mountain bike…
