Nanoelectricbikes Reviews 

I never normally write negative reviews. But I am perplexed by the predominance of positive reviews for Nano bikes, whereas I have never had a worse experience with such a significant investment in a British-made product. The two batteries I bought BOTH developed faults within the first few rides. Despite Nano insistence, that there was no problem, the (Bosch) batteries are not intended for this application. Bosch obviously can’t/won’t help. Nano did offer to sell me an alternative recovery-CHARGER - which took about a year (and many reminders) to send to the wrong address. When I tracked it down it was an off-brand item without a fault trip - effectively bypassing the problem. Rather disconcerting for Li batteries that are being used in a non-standard manner but I persisted with it. However after a few miles I have a new problem in that the bespoke Nano connector block fails to maintain a connection. Apparently this is common and I’m trying to find further hacks on line. On and off, I’ve been trying to use this bike for five years and have never had more than a few weeks’ occasional riding without hitting a seemingly insurmountable obstacle with a proprietary electrical component. It’s not what I hoped for and in my experience (which is not unique, it seems) Nano respond very slowly, if at all. You may wish to support local UK-based engineering businesses but in this case, it may be kinder to put it out of its misery. Go elsewhere.

Product was very good, to the point that I ordered a second kit when the first was damaged in an accident. Held up well to the rigours of a long train/bike commute across London and the Home Counties. Support with Lynda was top notch. Unfortunately, in line with other comments, the change over to Tony alone in Wiltshire seems to have left him a bit exposed. I had something go wrong with the 2nd kit, sent the wired bag back for investigations on his instruction then heard nothing more back in spite of emails to chase. Decided to cut my losses as I didn't want the stress of trying to remedy via an uncommunicative firm, and my method of commute was shortly to change anyway. Would suggest getting more hands on deck or utilising the ones they have better.

Had a Nano system on my wife’s Brompton since 2018 on a self fitted kit. The system has been a brilliant enabler, flattening the hills of Sheffield. It’s been generally very reliable, one off issues with pedal sensor and switch which I’ve sorted. Service was really good when it was run by Lynda from Leamington, and I’ve had some support from Tony (the original developer) to help me change the battery system from obsolete “Oregon” batteries. However, I note other comments regarding ongoing support; meaning we will sadly be looking elsewhere for potential future replacement. If you are practical, the Nano is a great way to learn about electrifying a bike in a clever and reliable way

I purchased a conversion kit for my Brompton and was very happy for a year or more, then a fault developed and I was unable to get any response from the company that had moved from Leamington to Malborough. At the moment I am in a situaiton where I have paid for new parts but have received nothing, and am unable to get a response from Tony Castles, who is listed as director at companies house.

Been using the Nano for a couple months now, and it's a solid product. There's a large hills on my commute, which is rough on a Brompton, but the motor carries carries me through, so I don't have to get off and walk it up.

I can get about 2-3 hours or of the battery, with light use, but the large hill drains it pretty quick. Overall I'm happy with the product, and while Tony has taken awhile to get back to me at times, he has delivered.

What a brilliant piece of kit. Had mine for 7 years. Worked brilliantly. Great that you can use normal electric appliance batteries as well as others. I have had occasion where a bit rattles off and the electrics don't work but Lynda and the crew provide amazing helpful support. I had a battery wear out and Lynda helped with a new connector to allow me to buy a new Bosch 36v battery. For the money you pay, AMAZING value.

I’ve had my Nano for around 10 years now and travelled Thousands of miles with very little trouble. All problems have been dealt with in a friendly efficient way.
The Brompton with a Nano kit is unbeatable in my opinion.

I've now had my Nano for getting on a year - Lynda was super-helpful and it's been an excellent bit of kit to use. It works exactly as expected and has been reliable so far. I initially ordered a large bag - decided a small one just for the battery was better, and Lynda sorted that. I've found the small bag works very well. Many thanks

I recently had a nano conversion to my 6 speed Brompton. Lynda was super helpful from the point of my enquiry right through to the end. I opted for Nano to fit the kit using the service where they send a super safe box to put the bike in. It was a seamless experience. I'm delighted with the bike. Having the option to add a bit of power is ensuring I opt to ride my bike over driving more often. Brilliant service

We have two M6L Brompton bikes we wanted converting to E-Bikes to make them more flexible for distance riding in hilly location having struggled to climb 10% gradients on them recently in Cornwall. Having done a lot of research on various aftermarket installers we opted for nano electric bikes. From first contact with Lynda for a quote for having the two bikes done, through to installation at Leamington Spa went extremely smoothly. Before final selection of types of throttles and control panels we were able to test ride bikes fitted with the various options. Once our decisions were made, Brian did an excellent job installing them. We have now done a couple of short rides, which include gradients of 11% and the conversions enabled us to climb them with ease. We are very happy with the nano bike installations and the standard of service and communication from both Lynda and Brian and would happily recommend them to anyone considering an E-Bike upgrade

In relation to the Nano fitting of my Brompton.
First I would like to thank Lynda Power from Nano electric bikes for facilitating the operation and administration. She made the whole process from initial enquiry to arranging a suitable workshop for the ‘fitting out’ of my bike go like clockwork.
Also, a big thank you to Brian Perkins at the Leamington Spa workshop for his hard work and expertise. Brian did a great job of fitting my Brompton with a nano system.
I won’t hesitate to recommend Nano Electric.
All the very best

Excellent service, neat installation. Efficient collection and return. Helpful staff. Highly recommended as they have given my 12 year old Brompton a new lease of life.

Nano excellent alternative to Brompton electric with a massive saving on the cost.
I don’t like the way Brompton has geared it’s market to what appears a non customisable and expensive view to allowing current customers upgrade there bromptons to electric why is this ? Any Brompton owner will tell you this is not unusual because there are so many cost effective and quality aftermarket products out there to choose from so why bother?.
I have done my homework when it comes to comparing what system offers the better value for someone who is just after basic but effective option and the nano system then make no hesitation the nano system from nano electric has to be the perfect choice.
Lynda from nano cycles provided excellent advice and help when I placed my order and Thomas from fix my bike white city was invaluable when it came to fitting the nano to my Brompton a big thank you to you all.

I've had a few interactions with Nano and I was impressed each time. The first time was ordering my Nano conversion kit (to be fitted at a bike shop in Manchester) and Lynda was very helpful and prompt in answering my questions. I'm very pleased with the bike. I live in Sheffield and it gets me up the hills without either me or the bike breaking a sweat. This is compared to my previous ebike (which had a Bosch mid-drive) and an official Brompton Electric which I test-rode - neither of them could handle the hills as easily as the Nano.

The next interaction was because I wanted to try the display-only mode rather than throttle, so I needed to purchase a brake sensor. Lynda promptly answered all my questions again, sent out instructions and the sensor, and quickly sent a replacement when the first got lost in the post - no fuss at all.

Finally, I wanted to try a smaller bag (having originally got one of the larger bags converted) so I ordered the pre-wired Ortlieb Ultimate 6. This was again sent out promptly and arrived the next day. Lynda even used a tracked courier to ensure it arrived safely.

Very pleased with my experience overall and happy to support a small business.

Thank you for your reply Nanoelectricbikes. I'm glad I've made the right choice to get the 4ah battery I do hope it lasts a long time.

The nano Brompton conversion kit is fantastic I have had mine for 11 years without problem. It was fitted by a third party.

4 years ago I decided to replace the heavy battery with Bosch 36v 6ah battery (purchased somewhere else) I bought the conversion block from Nanoelectricbikes but after just under a year the battery failed. I was able to get a replacement battery under the Bosch guarantee but this one has now failed so I have had to buy a replacement. Three batteries in four years is not good! Something is going wrong here but I emailed Nano Electric Bikes after the first battery failed and they said they haven't seen a problem with anyone else.

I have looked through reviews on trustpilot and someone had the same problem with 6ah battery and so they suggested to go for the 4ah which I have just ordered so fingers crossed this will work. If this is the case then Nanoelectricbikes need to stop recommending the 6ah battery.

Other than the problem with the battery everything else is excellent and I would highly recommend the nano Brompton from nanoelectricbikes.

It is an absolute lifeline for me as I have reduced mobility and it's the only way I can get out on my own. I just hope the new battery will be more reliable.

After much deliberation between all the competing electric Brompton conversion kits, I settled on Nano. Why? It seems to be at the sweet spot between all the options because of: (1) price (2) motor quality (3) use of non-proprietary batteries (4) ease of install (I did it myself in 5 hours or so - and didn’t fancy sending my bike off as some companies require) (5) delivery time. For me the most important thing was the ability to use power tool batteries whilst retaining my luggage block with the battery being inserted inside my existing bag! The controller is unobtrusive and enclosed in an attractively branded pouch. The icing on the cake was supporting a small UK business.

Lynda was very helpful. Nano even loaned me the crank puller/bottom bracket tools free of charge. I didn’t experience any issues during install, but was comforted that Lynda was on hand if I needed her.

I modified my 2017 M6L. A few quick points: No need to widen forks for the motor. Very comprehensive instruction manual. Motor runs up to 15.5mph with no difficulties. So long as you reverse the display bracket it fits on the bars without moving anything else. No noticeable drag on the front wheel when not powered by the motor. I seem to get about 12 miles in central London from the 4AH battery on a leisurely cycle. Quite a bit more when pedalling properly. Overall a great service from start to end. 12 month warranty on the motor, and I’m reassured that if anything goes wrong it will be sorted.

Things Nano could improve on? Nothing really product wise. A Video install guide would be useful from start to finish (the manual is great but on a couple of occasions I had to read it a few times to understand what was needed , and many of the bits did not apply to my bike ) I think with a video I could have installed it in half the time

The bike is brilliant and the support is spectacular!
I had my bike converted by Nano (in London) about 4 years ago and it has been wonderful. Of course it is a little heavier but the arrangement doesn't obstruct the superb Brompton fold and putting the battery in a conventional Brompton bag works really well. The battery is a standard 36V Bosch power tool one, so replacements are readily available if needed at reasonable cost.
A few points:
- I bought a 6Ah battery but it failed on me, I think the power density was too much and it overheated, so I suggest stick to the 4Ah version (which is also airline-permitted, when we can travel again!)
- with a rear rack and bag as well as a large front bag, it has excellent carrying capacity and rail-bike trips work well
- a couple of times I've found myself in rough circumstances (eg hastening for a train on frozen roads). With care, a low speed setting on the motor plus a low gear (all-wheel drive!) gave unexpectedly good control and I made surprisingly good safe progress.
- minor hiccups have been resolved with excellent support and advice from Lynda

I've had a Nano electric conversion on my 30-year-old Brompton for 10 years. I'm now on my second update, having swapped from throttle to pedal sensor about 4 years ago, and the freewheel in the motor has been repaired by them once.
Having been given a new bag for it for Xmas, I needed a conversion kit for the bag to allow it to hold the small battery and connect.
One email to Lynda Power at Nano confirmed they do them. She replied with a price and, after confirmation that I wanted the kit, an invoice.
I think Lynda had posted the kit even before I'd transferred the money.
It looks easy to fit, and has comprehensive instructions.

On a general note, even though Brompton now do their own ebike, if you have an old Brompton and are beginning to find the 16" wheels hard work, I'd recommend the Nano conversion. It was easy to fit, and even allowed me to convert the bike to single speed.

Recommended, and Nano bikes have always lived up to expectations.

I've had my nano kit fitted on my six speed Brompton for about three months now and I must say I am thrilled with it. It actually encourages me to ride my bike more as it is so much fun! The kit is very easy to fit and looks good too. The silver hub on the front wheel is very smart and I think it looks much better than the one fitted on Brompton's own electric bike. Acceleration is smooth and make riding uphill easy peasy, and pulling away you get a nice boost. Overall, I'm really happy with my nano kit and would definitely recommend it to anyone thinking of getting one. Great fun!

I love my Brompton even more with the addition of nano power! the service from nano has been really exceptional. I wanted a way of converting my bike that wouldn't make it too heavy to ride without power for the exercise, but get a bit of extra help for longer journeys or on hills etc. The nano does just that - it makes the brompton much lighter than a lot of electric bikes out there and feels great to ride both with and without the power running. The help from Nano in deciding what to go for and whether to make the investment was the best I've received, they were patient and willing to answer my many, many questions. Neil at Fix your Cycle in London was similarly friendly, kind and really helpful and responsive. The product and experience from start to finish has been perfect. Thank you!
