Perfect bike just need to lose the weight :-)

4 months ago

I am a long time fan of Brompton. I travel a lot in the USA and Canada. After work, instead of staying in Hotel jump on a bike and explore, exercise. It's so convenient to go to Restaurant grocery store so I don't have to eat Hotel food which I hate after 12 years. Now the G line. Its the same concept, just kinda different :-) I am 6'3" 210 pounds male and regular Brompton felt just short a bit for me so I look like Elephant on Circus bike :-))) It's like, you wear Shoes Number 12 but have 11 1/2 they are ok but a little bit tight....... G line is 12 :-))) Feels great, drive Amazing if you intend to use Bike more on gravel keep the original tires they are great I switch to Continental 1.75 as I mainly drive on asphalt. 8 Speed plenty for any type of riding, I do have a bit issue with proper adjustment of Shimano hub but work in progress .... With original tires I rode 30 minutes around a state park through different terrain and its perfectly cool but don't plan to use the G line just to do that…Continental ones on asphalt drives like Rolex :-) It is on the heavy side. My regular Brompton is 10 kilos G line is 14 bit difference. Nothing negative, only what would be nice to see in next generation is lighter material, shred some weight will make this bike ultimate foldy
