Question: does it have coaster brakes
Document: So I started looking online at  bikes in the $150-$200 range but most of them came with hand brakes that I would just take off anyway. So I decided on the Retrospec Siddhartha because even though it was a little more money, it looked good, had just the type of features I was looking for, and the components seemed like they might be a little better quality and maybe I wouldn't have to start upgrading parts right away.So the box arrives and it has a few punctures in it.
I used to be a really avid cyclist and still own a couple of very expensive bikes that were pretty good 20 years ago. I  decided to get back into cycling but wanted a simpler approach to cut down on maintenance and to really get back to the basics of cycling with a coaster bike. The whole idea of less fiddling around with the bike, and spending more time riding was what drew me to this type of bike.I started looking at cruisers but wanted something more agile.
this is the best bike ever. its so chic and functional and i ride it everyday! black is back! Its really easy to put together also.
everything is great so far. shipping was fast. package was not torn or anything. however, i have not been able to ride it because it's apparently missing a part. the little metal part that connects the handlebars to the rest of the bike is missing. i can still put them on but it's an awkward fit.
Well deserved lower part of 4 star.
We'll see how she holds up during some real rides in the Spring. I still have a thunking noise when I stop pedaling that is annoying as heck. I called Retrospec, and to their credit they tried to be helpful and I even talked to one of their mechanics that was knowledgeable and a really nice guy. But at the end of the call, it still came down to me probably having to take the bike into a shop and have someone look at it.So was this a good deal?
The seat didn't look too bad, but the grips look like something off of some toddlers Wild-West themed tricycle. Those gotta go. Retrospec would have been better off going with some basic rubber grips in brown or black.I'm no bicycle mechanic, but I've repaired and rebuilt a few in my day so I know a few things about bicycle assembly and adjustment. The first thing I noticed once everything was unpacked was that this bike was going to be completely unrideable without some major adjustments.
The bike might be fine. I can't speak about it yet. I received the wrong bike twice. My first order was almost two weeks ago. And I am returning the item a second time. At this point, I considered canceling the order but I don't have that option. So I am stuck in this kafakesque ship and return dance. I'll update when this is resolved.
So watch out for that. I luckily have a bike shop down the street and a couple of bucks later had a replacement tube.The looks of the bike are great. I get compliments on it from just about every new friend who sees it. Just looks classy. I leave it outside and the leather (or faux-leather) still looks fine and I haven't noticed any rusting.Riding it is comfortable and smooth.
So the holes in the box were from the contents slamming against the sides in transit. Not from being impaled by something else. Remarkably, the parts were in good shape once I removed everything from the box. I bought the large frame in black, and everything looked pretty sharp. But what's up with the  "leather" handgrips and seat? I wasn't really expecting real leather on a $300 bike, but why lie about it?
Answer: yes
