Brompton Electric G Line: One minute review
Bumpton is only one year away from celebrating 50 years of its establishment. This is a completely bike development experience, but Bumpton’s entry into the electric bike market recently, much happened in 2018. Despite this, they are already making something Best electric bike Some of the best folding of e-bikes on the surrounding and of course the market.
The brumpton formula has been largely unchanged despite releasing the electric versions of C Line and P Line, but the All-NUG line is a radical departure. Frame shape and classic 3-point folding mechanisms known for the company, known for the company, but it claims chunker tires and broad handbers for thick paths.
After using it as my main commuter bike for more than two months, I am still torn how I feel about it. On the one hand, engineering and quality are there to give a great ride experience, but I do not know what to do of off-road enhancement. Although it will handle gravel, cobles and single track better than other bromptons, is anyone really going to ride the proper dirt and ride on the tough area?
I think only time will be able to answer the question, but from my perspective, it is definitely the most comfortable and reliable brompton e-bike I have ever used. Comprehensive handbars make for more approximate handling, while chunkers do mild work of pits and uneven roads. I will not take it off-roading, but I will definitely do not trade it for C or P Line.

Brompton Electric G Line: Price and Availability
- $ 3,300 USD / £ 3,499 UK / $ 7,250 AUD
- Expensive for a folded bike
- Premium build quality for price
The cost of the brumpton electric g-line keeps it firmly between the price points of the C line at the lower end and the P line at the high end. The price is hard for the stomach, but for money, you are guaranteed by excellent-grade materials and fantastic construction quality. Simply put, they are worth the previous and well money.
Brompton Electric G Line: Design
- Chunky tire
- Wide handlebars
- Four speed setup
The iconic three-points of the brumpton continue to function well despite the folded wheels, increase the size of the tire, and the wide handber. As a result, it can be popped in the back of a car or in a train, although not as easily as a small brumpton model. You also get the height of an adjustable seat and a long handler stem, and there is a 250W motor that leads the e-bike. In many ways, the G line is like every other brumpton.
But this is also, in many ways, it is very different. The most noticeable of all is the 20 -inch wheels. They are not too large to affect the smooth folding mechanism, but they are large enough to stand out. Chunky Schwalbe G-Ol Round 54-406S not only thanks to a tan wall finish, but also puncture-resistant. I did not have puncture at a distance of more than 600 miles and is never expected to be united soon.
Then there are broad handbers which are custom-designed for the G Line. With tires, it can only be my favorite thing about e-bike. After riding several Brompton bikes, I can sincerely say that the G line is the most stable so far, which is due to the part of the wide handler.
G-line is also equipped with hydraulic disc brakes, the first time for bromptton. In my opinion, the decision to go to the hydraulic has been over -overdose. I found that the brakes are reliable in all weaving and there is no need to fulfill any adjustment or maintenance on them. Will Brompton go below that route for future product release, only time will tell.
Finally, the G-line is a four-speed setup, which has historically been the Go-Two number for Brompton. After carrying bikes in different types of areas including some very severe hills, I would have preferred some extra gears. There will be two ideals at two ends, taking up to eight. With the other range of Brompton, I think it will introduce a model with more gear at the latter date.
Brompton Electric G Line: Performance
- Certainly a dedicated gravel is not replacement for bike
- Large size and additional weight affects portability
- Maximum stability on approximate surfaces
I have thought long and difficult to assess the performance of this new Brompton e-bike. I flipped it between behaving as any other folding e-bike and assessing it on its off-road properties, and I am not sure I really landed yet. This indifference is probably due to the fact that in an attempt to make a gravel bike, type, they have actually compromised some of its portable properties.
Let me be clear. This is no replacement for a dedicated gravel bike. On a push, you can demand it as a computer bike from Monday to Friday and some minimum wooden routes over the weekend. But as far as the g-line will take you.
Off-road boundaries, the center around the lack of stability, especially when exiting the saddle. Comprehensive handbars and large tires help a bit, but there is not enough anywhere to really push the bike to the limit. It was also not enough to distribute me in more extreme conditions, such as through thick soil. As I have said, simple trails with limited obstacles are fine, but serious off-road enthusiasts will be abandoned.
Everything was very daily on my daily traffic. In fact, it was actually the most performing brumpton e-bike that I have ever riding. I loved the stable handling and confidence to go up and down. The extra weight provided a sense of security, although it is definitely less nipple than the C-line or P-line model.
But at the end of any movement, it is required to bend it either in the office, in a train, or behind the car. This is where I had some problems. At more than 16 kg, it is much heavier than other brumpton. I am quite fit and healthy, but I still had to be careful how I am picking it up. The folded size is also very low compact, so if you are expecting it to stored in tight places, I would recommend checking the dimensions.
Overall, I enjoyed my time with g-line, but only when I stayed away from gravel tracks. Buy it if you want a more stable brompton ride and are ready to handle excess weight.
Brompton Electric G Line: Battery Life
- 20-40 miles per full battery
- Four hours recharge
- Battery weight makes front-loaded
The limit of this e-bike is similar to all other brumptons tested by me. This is not surprising given the same battery capacity. If we are going to drill down in number, then in fact, the G line is really slightly worse, perhaps due to additional tire friction. As a result, I managed to get only a maximum of 40 miles per charge, with 20 miles more common. I love full pedal help, finally.
This limit can be very limited to something, but if you know that you will regularly reach a charger, it will not cause too much problem. With a daily transport of 14 miles, I found myself to recharge the battery in most days. An empty-to-complete recharge takes about four hours around four hours and one is ideal for a day recharge between the two legs of a movement.
The battery sits in front of the e-bike, which helps to balance the steering slightly, but is far from the ideal when considering the overall balance. This is especially the case if you try to lift the bike.
On the previous brumpton e-bike, I experienced a battery cutout when I went to big bumps, but I had no such problem with this G line. I am happy, especially given the bike designed for off-roading. The battery is easy and easy to remove and install, although I will still prefer a safe solution to lock the battery in place.

How I tested Bropton Electric G Line
After testing several ‘standard’ brompton e-bikes, I was pumped to get my hands on the first of this new line of the bike. After unpacking it and revealing it, I made the e-bike in my main form of transporting for more than a month. Living in rural areas provided enough opportunity to take off-road, while my daily traffic enabled me to test it in a more predicted environment. As part of the review, I covered a distance of several hundred miles.
