Kopps cycle has saved my behind so many times. The amount of times they've been able to provide the inner tubes I need is insane. Highly recommend this spot for even minor electric scooter repairs! read more

Highly overpriced service, look first into other options in the area I took my son's bike for a tune up as the gears were skipping a bit. They told me it could cost between $80 - $120, I found it a bit on the high side but decided to go ahead, they called me today to say it was $120 ... no major intervention in the bike other than lubricant on cables and gears tune up. I have taken my bikes to this place before and to other places in the area, and was never charged this much for even much more deeper maintenance, furthermore the outcome is not the best ... if you can, avoid this place read more

Kopp's fixed my sons bike in a timely and cost efficient manner, offering options during the process which was seamless and stress free. Excellent communication and service. Reasonable and reliable. Highly recommend! read more

I was not impressed by this store. They did not have a very wide selection of bikes. But more importantly, I walked in and browsed. Several employees passed by me, yet nobody offered assistance. I would not go back there, mainly because they did not care to make me in to a customer. read more

Walked in with a few random questions about a bike I purchased recently from fb marketplace. KJ was great, super helpful, funny, and patient. It was a little pricey but for what I got, I'd say it was worth it. Hope he gets a promotion or something read more

Quick and helpful staff; gave great advice and were straightforward and friendly. Absolutely where I would take a bike I needed to have serviced. I was looking for a gravel bike, which they didn't have any of when I stopped by, but it was worth it just to visit this historic bike shop. read more

BEWARE: they charge a lot and often will charge more than expected. I dropped my bike off for a simple tune up because my brakes seemed a bit off. I was expecting it to come out to about $30-$40 but when the person I dropped off the bike with quoted $60+ I just accepted that it was a bit overpriced. They told me they might change the chain but if they were going to, they would call me about it (since it makes no sense the change the chain as we go into winter season). But I received no call and when I picked up my bike I was told they had changed the chain and was charged $110, which was significantly over what I expected. If I had known they were going to charge this much, I wouldn't have bothered to drop off my bike there in the first place. read more

Just like an old fashioned bike shop should be. Small - personal - and with a lot of Bianchi.

According to their website (http://koppscycle.net/), the oldest cycle shop in the country. Hours: Tues, Wed, Fri 10-6, Thurs 12-7, Sat 9-5, Closed Sun and Mon Outside are some of the used bikes for sale, with the super high-end ones inside or to order (a small fleet of Vespas would be cheaper). Knowledgable staff, but remember that this is a serious bike shop, with bike enthusiasts. read more

I have to admit: as much as I talk the talk, I can only proverbially crawl the walk when it comes to working on bicycles. Simple stuff I can do fine enough but I really have no idea when it comes to cables and housing and derailleurs... Case in point: something was up with my derailleur, I tried to fix it, but things kept falling and loosening and slackening everywhere until I felt like my whole world was crumbling beneath my fingers and I had to throw in the towel. José (I hope I got his name right) was extra nice and friendly! I really don't have much to say except that I got my bike returned a week later with everything fixed and tuned up (beyond the cables that I brought the bike in for). Shifting is smooth like it used to be! As an added plus which I was not expecting, my wibbly wobbly wheels were trued. My bicycle got a full service tune up--everything I could have asked for. The fee came to ~$80 after taxes. For all the work done, I couldn't be happier. To note: during the sunnier weather, everyone is bringing their bikes in for tune ups after the winter--so it will probably take around a week for them to finish with yours. I'd imagine it's a lot faster in the winter when no one is riding. read more

Not sure how everyone keeps saying they're friendly? I walked in to rent a bike and was not greeted with a hello but rather a stare. When asking about rentals I was told "Not today because its wet outside". Wtf? It was sunny and had rained the night before. I hardly think it not being perfectly dry outside is enough reason to not rent out your bikes! Ridiculous. read more

I needed a wrench which bike shops can order but generally don't carry in stock, and I needed it in 2 days. I called Jay's cycles first, and they said they couldn't get the wrench in stock in my time frame. Then I called Kopp's and spoke to Charlie. Charlie checked stock at the warehouse, found the part I'm looking for, and told me he can have it at the store in my time frame (in 2 days). Sure enough, 2 days later, I called Charlie, and my wrench arrived on time! I went to the store, and people were friendly, and I got good service. read more

Once again the master mechanic Jesus fixed my bike so I could enjoy 27 miles in this gorgeous day!!!!

July 10 2015. I bring in and leave my bike there and go over $300-$400 upgrades with Jesus. July 29 2015 I call about the status of my bike. They first cant find my ticket, then said it was misplaced--in the completed pile. So now I'll have to wait on parts. August 17 2015 I call again. They can't find my name in the system again, not Jesus, and they don't know about the status of my bike. August 19 2015 (just now). I call and Jesus & he tells me that we're still waiting for the part (internal gear hub). I ask politely if I can cancel my order and he's quick to accept. 40 days without a bicycle in the summer with nothing to show for it; maybe you'll experience what I've learned: 1. The employees are very friendly. 2. Avoid situations where someone must order something. 3. Don't loose your receipt-ticket-stub (my only savior each time). 4. They said someone would call me back multiple times, but they always seemed to have waited until I called. read more

Went to Kopps after going to a store in Somerville to have two bikes serviced. My wife and I are leisure bikers, around the neighborhoods, to the parks and shore with the bikes. We are not serious marathoners. When we brought our bikes into the Somerville shop we were laughed out. Our bikes are 10- years out yes, do the need a turn up, yes can we still ride them yes, but at Somerville, they wanted us to get new bikes, said they could not make our ride well and quoted us a price that almost seemed like we had to replace the bikes. When I said I"ll take them for a second estimate the tune changed so I knew they were con jobs. I went to Kopps. We were treated politely and they said our bikes were perfect for what we wanted to do and they can make then good as new for much less than what was quoted @ Somerville. The turn around was 5- days (no problem) we paid what they quoted. Because of their honesty, I brought a helmet and a lock, which I could have gotten cheaper @ Walmart, but I like to support the little guys especially when they work honestly and treat one with respect. I will use Kopps for all my biking needs. They earned it! read more

Awesome service and product! These people spend time talking with you to discover the bicycle best fit for you and your needs. The owner even helped me out to my car, put my car rack on, and loaded my new (used) bicycle! Great, friendly and knowledgable staff. Exceptional customer service - I couldn't recommend them enough!! read more

Buy your next bike at Kopps. I just did. Really neat bike. And they serviced another one for me. Great service. Not pushy but knowledgeable and quick turnaround time. Was told in the old days they sold a hundred plus bikes at Christmas. Now not so many. More wii and Xbox i guess. And more obesity and diabetes as well I suspect. Get off the couch in 2013. Get away from Facebook and all the booze and chips and cigarettes and go ride your bike around Princeton. If need a new one, buy it from Kopps or ask them to tune up your old one. BTW, free off street parking right next to the shop that fits a handful of cars. Always an open space when I was visiting the store. P.s. got a cool bike rack from Thule. read more

Updating my review. For the second time in a row, the final bill for the repairs came in well above what I was quoted at initial drop-off. The quote for replacement of a derailleur was $40, and with that plus the addition of some new handlebar tape, it came in at over $80. This time I didn't have the energy to argue and just paid it, but if I'd known the real price they planned to charge me, I'd have just bought the parts off the internet and done the repair myself. I'll still choose them over Jay's as at least they're nice about it and they did a good job, but this is starting to look like a pattern. Ugh. read more

Very friendly staff! Got my sons bike fixed here (brakes and tires): fast service and a reasonable price. Used to work in a kids consignment store around the corner and sent moms with flat tire strollers here: they do it all! read more

Cool shop. For such a small place it has a pretty good selection of commuters and higher end road bikes here. There's a bunch of NOS Campagnolo parts in box behind the front desk, so if your wallet is weighing you down a bit and you have a vintage Italian frame to build up I'd recommend checking them out. read more

I've brought my bike in a couple of times to Kopp's and every time they've been knowledgeable and helpful. They're on the expensive side but can work quickly. Most of all, I've never left the place feeling like an asshole for not knowing all the parts of the bike. read more

I guess, like most above if your looking for some repair work with a quick turnaround, or your a "serious" biker - it serves your needs. To me, with the information of some internet research, showing up on a rainy weekday with no one else in sight, it was one of the most disappointing, if not simply rude retail experiences I have had in the recent past. Wal-Mart - (who may actually have something to suit my needs, but price not being my main concern I'd rather shop "local" and have personalized options), would be better. Could be that's why across he country they put places like his out of business? My having an idea of what I wanted - and I guess it not being what they wanted o sell that day...made me immediately dismissible. After deciding some brands a "cruiser model" may work 2 of them quickly walked me down a row of bikes, ignoring my interest in any, stood next to me at a wall, couldn't remember - or didn't have what they brought me there for and were seemingly confused when I asked which it was they brought me to see. I guess to help explain what I was there to buy I said my research showed a Schwinn model 411 that was interesting, but yet would need some specialized changes. Apparently insulted that I didn't know "They don't carry Schwinn..." nor able to understand I was mentioning it as an example of the idea, I was dismissed. So pro's (or maybe those who need a repair that you can't do yourself) I guess it's the place to go. But if your just interested in starting - or like me - getting re-involved - and want to buy the appropriate thing with some personalized attention for your indiciual needs...you may do better at K Mart. Certainly, the week before I was more welcomed by the sales guy at Sears, even when my girl and I explained we were just looking. If you do wander in - heaven help you if you see something you find interesting ...as I did (before really understanding how unwanted my business was), it was met with one of those "how could anyone not know..." non-explanations. That was when it became clearer I do not qualify to be a customer. Fine by me. Or maybe it's just they are intimidated trying to compare (what they can't even find) to a Schwinn? But I'll just have to have someone else explain that. read more

I went there last weekend and needed a minor type adjustment to my brakes and a new rear tire. They were backed up and told me that it would take a few days to fix, but when I told them that I was going away on a trip with a few friends, they turned it around for me next day. That was very cool. I will be back there. Nice group of folks who work there! read more

I bought my first real bike - a Peugeot - from Kopp's in 1984. I bought my first semi-serious road bike - a Schwinn Circuit from Kopps in 1986. You might pay a bit more here than at some other shops, but it's worth it. They are the bike shop for real bikers. Good service, good advice. I now live in Lexington MA and I buy from bike shops up here. But when I'm in Princeton, I still buy from Kopps (picked up some gloves last week-end). They have the stuff that I'm looking for and the staff is very friendly. I had a very nice chat with one of their staff about a fixie they had in the shop which was awesome. The only reason that they don't get five stars is that they could do more to organize bike rides and support a local biking community. NBX in Narragansett RI does a lot on this front. That all being said, you have to support your local bike shop (LBS)! PS Kopps' service and attitude is much better than Jay's. Jay's seems to be out to make a buck no matter what, and the sales staff just doesn't seem as well versed. read more

We were in a panic a few months back because we couldn't get our pedals off on the day we were flying out to CA. Ran down to Kopp's and they got them off (with more leverage) immediately and didn't charge us! Fast forward to last Friday: Popped a spoke and rim was our of true. Took it in late Friday near closing. Being busy on Sat. they stayed in shop until 9:30PM (normal close is 5) to get my bike repaired (had a gear issue also) so that I could ride on Sunday. Awesome!!! read more

Very friendly and helpful staff as well as excellent service! I needed a stem riser for my bike, so I checked with Kopp's Cycles. I was skeptical at first because prices in Princeton tend to be much higher then elsewhere. But it turned out the part they ordered was reasonably priced (compared to offers on internet shops). I like to do maintenance on my bike myself, but I would not have had the tools and the hardware to install the stem riser which involved extending some of the brake wiring. Kopp's Cycles did an excellent job at fitting the part, and in the end didn't even charge me for it! I will definitely return to Kopp's with future bike-related issues. Wholehearted recommendation! read more

I came in today at the last minute when I discovered my bike computer was missing a piece needed to attach to the handlebar. Needed this done that day and it was already mid-afternoon. Needless to say the gentleman who helped me, I believe his name is Andrew could not of been more pleasant. Bike was ready in no time, he'd not only taken care of the issue but noticed the battery for the computer was dead, put air in the tires for me and had it trip ready. All at a very reasonable price! read more

I've been a fairly serious cyclist for 15 years or so and I've never encountered a friendlier owner or staff. Charlie the owner will never sell you stuff you don't need and his prices are always fair. I bought my second bike from him (the previous one was 2 bikes and many years ago) last year and I am very happy to call this shop my cycling home again. Got a very nice deal and was able to get the bike tailored to the terrain I ride in with no hassle. Plus-what's not to love about Bianchi bikes. read more

I tend to find independently owned bike shop folks good people. The guys at Kopp's are exceptional. Prices are fair and the service is great. Wish I didn't live out of town and could make this my regular shop. Jesus went far above and beyond the call of duty and is the best I've met in my 30+ years of riding. read more

Lovely, friendly shop. Have gone in multiple times expecting to pay for small repairs and instead getting friendly help for free. This may be a "serious bike shop" like the other reviewer said, but I'm no bike expert, and I've never felt out of place or unwelcome there! Today bought a nice hex-key set, and will go back for other bike needs in the future. read more

Be sure to get the price quoted before they begin work or prepare for a surprise. I show up with a flat tire and ask if I can get a quick fix. Guys says can I wait for tomorrow? I say no, I'll just buy the tube and do it myself. He says, well upon second thought I can do it real quick, no problem. I say thanks. A minute later he is done and has billed me 15 bucks to slap in a tube I could've put in myself in the same amount of time. I was like - what?!? I just wanted the tube and a quick pump. The tube cost 8 bucks. Totally disproportionate cost and dishonest in the way he got me to pay three times more than I thought I'd ever pay for that type of fix. Bad way of doing business. read more

Charles Kuhn runs a great shop with his wonderful staff. He helped me pick the perfect bike for my 5 year old (red fuji absolute 20) The price was in line with what i could have purchased for online as well. When my son rammed the bike , he fixed it and made it look like new again! Thank You read more
