I received my Revos ebike conversion kit in July 2022. So far so good. It’s really good fun. As soon as you start pedalling the wir of the motor kicks in and you very quickly accelerate up to 15.5mph. Sometimes a little bit more. I purchased the kit using eBay, making an offer which was kindly accepted. It proved cheaper than the Swytch bike kits for a similar range, approx. 25 miles. I’ve fitted the kit to a Boardman MTX 8.8 hybrid bike fitted out with panniers. This is my work bike that is used to commute to clients homes. I live in a rolling location on the edge of Charnwood Forest so returning home after a days gardening or handyman jobs is very much made easier with my Revos system. Well done to Hugo for turning this invention into a commercial product with the support and assistance of his dad Mark. There is tire wear caused by the Revos motor, and the front derailleur gets covered in little pieces of rubber and dirt thrown down by the motor drum. This can easily be cleaned off and the tire still lasts a fare amount of time. All in all I’ve been very satisfied with my Revos purchase to date, it’s a lot of fun. Fitting the kit was relatively quick, although the Lollipop PAS sensor magnetic ring proved quite difficult to set up. It still needs tweaking since the gap between the magnetic ring and PAS sensor isn’t completely even in distance 1-2mm during an entire Pedal revolution.
Not long after buying a Bristol Bicycle the company went bust and I started having problems with intermittent drag. The motor manufacturers, Revolution Works, thought it may be battery related so loaned me a new battery for a week before having the bike in for repair. Customer service has been exemplary (I'm tempted to put a Revos on my non-electric bike!).

Nice device, arrived yesterday and was pretty easy to install. Tried it out yesterday and first impressions are quite positive, it’s good fun,very quiet which was a pleasant surprise. Need to use it some more before giving a proper review. But it seems like solid quality build and a nice riding experience thus far.
It gets you up to a pretty decent speed with little to no effort. Up a steep hill still needed to get in low gear but was still relatively easy to go up but wasn’t for ‘free’ still. It makes me feel like a strong cyclist because I can put in effort if I want and I’m flying, and if I take it easy I’m still flying pretty much.
I felt the 15.5mph assist limit kick in for a moment on a down hill then you get no help, bit of a killjoy cause you can definitely feel the plateau but that’s the law here in NL anyway.
It turned out that REVOS unit was not suitable for use off road on bridleways etc due to mud or heavy dust on tires contaminating the friction drive. Agreed partial refund took some time.

So I decided to use the cycle to work scheme to get a electric bike for my 5 mile round trip to work daily. I found revolution very helpful with the process of ordering the bike through the scheme (the scheme is a little confusing but it worth pursuing). I have ridden steel hardtail bikes for the last 30 years, so was looking for a lightweight electric mountain bike that did not scream electric bike at you, The whippet seemed to fit the brief well.
The bike was delivered well packed and only a small amount of fettling to have it on the road, I had to adjust the gears and the front disk needed nipping up slightly as there was a little movement from new. But you expect a new bike to need a little fettling as cables bed in.
I have covered just over a 100 commuter miles, so it’s early days, but first impressions have been very good.
I am 5ft 10 and the bike rides spot on for me, probably a better fit than previous bikes I have had in the past. Handling is excellent the conti tires, I like the reflective loop on the tire which suite commuting and offer fantastic grip without too much road drag.
The bike is obviously limited to 15mph and the 250w rear motor with pedal assistance feels totally natural and is very smooth. Three power levels, the lowest power level, level one, removes the weight of the rear hub and battery and it feels like a regular bike to ride, this is the setting I use on the flat, switching to level 2 power and you can feel the assistance, it feels like you have the wind behind you pushing you along, on level 3, you can easily glide uphill at a reasonable pace, which for me was the main reason I wanted a electric bike, to give me that help up the hills.
I find the battery lasts me a week between charges, on my hilly commute I cover roughly 25 miles a week, at the end of the week the bike is still indicating two bars of battery life! Being colour blind having the light change from orange to red to blue for fully charge really helps to tell when it’s charged, charging only take 3 hours to fully charge again.
The bike grips are excellent offering great palm comfort, brakes are very progressive and offer ample stopping power with no sign on brake fade on long descents.
The bike loves to corner, offers loads of confidence and is a joy to ride on twisting paths, I am sure it will also ride well off-road if I wanted it too.
Gearing is spot on, no real need to change gear, apart from some of the steep climbs where I drop a single gear, I have not had the need for the high granny gear but it’s nice to know it’s there if I need it on a climb and have no battery power left.
The only thing I would have liked to have seen was maybe a better solution for the use of zip ties for some of the cabling. A choice of different base colours would have been nice too. Plus I get a slight rattle from the battery when going over ruts in the road, but it’s not detracted from the ride, which is almost silent otherwise.
On the whole the bike has been an absolute joy to use, it cut the time of my hilly work commute dramatically and I no longer get to work covered in sweat.
If you had offered custom colours I would have loved a natural steel colour for the frame 😉

Because of the design of our fold up bikes, it was a challenge to fit the Revos electric bike kits. Anyway, with the assistance from Revolution Works (Hugo & Mark) I fashioned new brackets to fit the motors. The bikes are working well. Certainly a big help up hills. If you turn off the motors, you realise how much work they are doing. Steep hills are a bit too much for the Revos but we’re not that fit and have no gears on the bikes To be honest, last year, away in our motorhome for a couple of months, we hardly used the bikes but with the Revos conversion, the bikes are being used at last. A quality British made product with great support.
The concept is good in that you do not add any significant weight to bike. Cycling with the motor off with drum in position does mean much more effort, however personally I prefer to disengage drum for part of ride then when needed reingage the drum.
This is a great company - passionate about what they do - and making a brilliant product. Their bikes are really special. And I felt very looked after in terms of the process of visiting the office - test riding a bike and liaising with the team about what I needed - all the way through to them bringing the bike across town to deliver to my house to make my life easier.
Highly recommended
The product lives up to what they said about it, all the staff that work there are very professional and friendly.
The price of 80,000 yen is not very cheap, but I think it is cheap if you can enjoy the pleasure of riding a bicycle equipped with Revos.
First impressions (2 weeks in). Great bit of kit and better than I was expecting.
I’m a 60 year old 5’4’’ lady ( I can just about safely straddle cross bar when standing over) who likes to ride a road bike on group rides of 25-40 miles in the rolling North Somerset countryside. I was finding it increasingly difficult to keep up with the group and they were having to wait for me at the top of hills. Sadly the conversion kit doesn’t fit my road bike, so after speaking to Alistair and a brief trial of the Whippet I purchased mine on 12th April. The bike has done 130 miles so far and apart from a bit of vibration from the front disc brake (rectified by simply removing the wheel and replacing ensuring it was seated correctly in the fork) I am impressed. Today I managed 40 miles (total elevation 1100 feet) and display still showing 60% although battery indicator red so probably nearer 40%. I feel confident I can happily extend the length of my rides in future, and would consider carrying a spare battery if I really wanted to up the miles.
The controls are easy to use and the bike handles well.
The Whippet is very competitively priced.
Would definitely recommend and I’m so happy to be able to support this growing local business.
Customer service as it should be: quick to response, even on sundays, helpful with advice and they really do their best to help you with any issues or questions you have. I can only recommend Revolutionworks (and their product).
After hearing from my friends how satisfied they are with using Revos, I decided to buy two sets for my family. The customer service was very friendly, helping me with my quiery whether Revos would fit on my bikes, which it does. The products were dispatched promptly. All in all: perfect!
Had an issue with the battery charge indicator (still under warranty). Revos had the battery back and also loaned me a spare whilst they fixed it in a couple of days. Excellent friendly professional customer service.
Had a test ride in Bristol then ordered on line.
