Question: How much does it weigh? Pat
Document: I am really ecstatic over this bike. I have taken it out to ride several days now and love it just as much each trip. The shocks are definitely worth the extra expense and the ride is very comfortable. Soooo easy to open and fold away. I am 5' 4" and fit great on this bike after adjusting it to my size. Also I weigh 115 lbs and have no problem handling it by myself.
I vote for "excellent value". My previous bike was a Dahon folding bike that cost almost three times as much as this bike (but was stolen, and insurance would only pay for about $300)... and I actually like this one better, so thanks Mr. Grand Larceny.
This is not my first folding bike so I haven't really looked at it too much. There are a couple of sheets that show you how to disassemble, adjust and maintain pretty much everything on the bike. The print is way to small and it is hard to read.I do think that some documentation on how to assemble the bike would be nice. There is not allot to do to assemble the bike but there were no instructions on how to get it done. Put the front tire on.
I thought a folding bike would be much less of a bike. But the 26" Columba I bought from 2KSilver was as well equipped as any other bike I own. It actually had the bell as in all the bells and whistles...and reflectors, and smoothly working gears etc.The overall quality seems exceptional and the packaging and preparation was excellent. They were wonderful to deal with and the bike came quickly and as promised.
I like the bike very much real easy to fold and pack in bag to ship on a plane.It was nice to not have to deal with shuttles and a rental car. Although peoplethought I was crazy when I unpacked a bike and rode out of the airport.There was no additional cost for traveling with it, since it was consideredmy luggage and under 50 pounds. The bike also worked great for me on a50 mile ride from the airport to my hotel.
it's a good bike for the moneyeasy to fold and take every place inside the car as i use to ride with my son thats great
When I received the bike I was not sure how to assemble everything together. The written instructions that come with the bike are pretty useless. I went to the website listed on the owners manual and clicked on the FAQ link. When I scrolled down I discovered there are several videos that show you step by step how to assemble the bike. After watching these a couple of times, I was able to assemble the bike with no problems. I highly recommend watching these videos on the website.
This is a very nice produce, just the way I expected. However, this bike has a potential safety issue. the headset need to be tighten up every time. The screw in the head tube may be wear out someday, when the bike could be out of control. Hope the manufacturer will make a correction.
This is a nice folding bike- with big 26'' wheels.When I got the bike there was a problem with the ring, and shifting gears was not smooth at all. I contacted the seller and they immediately apologized, said that the installation probably had some problems, and that I can take the bike to the nearest repair shop to fix and they will refund me.The process was indeed very simple. I fixed the bike and received a full refund on the repair cost within a matter of days.
The item arrived very quickly. It was 98% assembled and the other 2% didn't take too long. The adjustment tools for the seat and handle bars are built right onto the part for convenient adjustments anytime. The gear shifting system works great. There are large hills where I ride and the gear shifting allows for a smooth effortless ride. Plus when folded it easily fits in most trunks and is allowed on the train.
Answer: yes
