I started -since I was 3 ore 4(?) years old- as a (BMX) mountainbiker,.. Since than I have many bikes,.. Mountainbikes,.. Gravel-bikes,.. and road/racing bikes like my latest purchase,.. The Twitter -with the 105 Shimano hardware- straight from the factory in Shenzhen in China. I LOVE this bike,.. The price / Quality ratio is something I couldn't find somewhere else. Al my compliments goes to the Twitter Factory in China!
I have only put 80 or so miles on the bike but it has been great so far. No issues. I was nervous ordering from china as I live in the US but everything went well. It took a long time to arrive but it was worth the wait. The wheeltop shifting has worked good. It's worth the money for sure. A little difficult to set up but it's been great and had no issues since! The bike isn't light compared to my carbon US bikes but for the price it's more than I could ask for. I got the green color with no decals and it looks really good! I honestly suprised how amazing the bike is. I'd definetely recommend buying this bike.
very nice bike love it
My bike is a 2020 Twitter Gravel V1. I bought the Hamax Outback Bike Trailer/Stroller, and I easily cover 25 miles with the baby.
Много добър велосипед на прилична цена! Пристигна добре опакован, сглобяването беше бързо. Единственото нещо, което не беше ОК е веригата. Имаше прещракване на някое звено, когато минаваше приз едната зъбчатка на задния дерайльор, но го оправих.
The bike arrived in Czechia in perfect condition. Really a lot of packaging material against scratches and shocks during transport. The journey took 25 days without any problems. After unpacking, the bike needs to be assembled - the frame is already assembled and adjusted. All tools are included. After the first ride, the bike is really robust and very nicely made. Everything works as it should and I have a good feeling about it. In the terrain, it behaves like riding on a cloud thanks to the full suspension frame :) The components are very high quality for this price - I have the HIGH version. The only downside with the EM19 is handling the battery / a little more difficult to remove and insert several screws through the tight frame. Maybe with the wireless derailleur version, this installation will be a little easier without the Bowden cable and other cables. Otherwise, I'm 188cm tall and thanks to the telescopic seatpost and 18" frame, everything works great. The quality workmanship of the bike frame with the combination of the lightweight Bafang M820 motor makes the battery range very sufficient for me! The Twitter team's communication was always quick for my questions. Everything went smoothly from ordering to delivery to my door. I can recommend it. Thank you Anderson for the communication and handling🙂
