Cosmo 2.0 is the fun way to exercise, go to farmers markets and do bike and breakfast dates etc with my husband of 40 plus years!! I sold my magnum cruiser because it was not a step through, in fact my best friend bought it !! My husband sold his ebike to her husband and he upgraded to the new this year magnum Bliss and he said it's his best ride yet!! Magnum e-bikes are reliable fun and the new colors are amazing! happy ebike riding everyone!
I received the item and I am very happy for your service
I have been using this bike to go everywhere and it has been incredible! This bike is really fun to ride and it beats sitting in car traffic! Used it for grocery trips, work commutes, joy rides; it's amazing and I highly recommend it for commuting and casual riding!
My husband bought me the Magnum Cosmo S and I absolutely love it. It is so much fun and a great way to spend time with the person you love.
I love this bike. The COSMO + is an easy to ride bike that allows me to ride further and enjoy the outdoors longer. The quality of the bike and the excellent customer service is top notch. Thank you Emily for your follow-up and excellent customer care.
I rented this exact bike while visiting my dad in Florida this summer and fell in LOVE!!! I had to wait a little bit before there were more in stock, but it was SO worth it! Customer service was phenomenal in helping me with a few hiccups in the beginning, but everything is perfect now, and I have been out riding everyday since! The best part about the pedal assist for me is that I have a bad knee, so I can still enjoy all the things I love about biking with a wee bit of help when I need it. Can't say enough great things about my Magnum Cosmo X!!!
Store owner replied: Hi Jeni. Thanks so much for your purchase and becoming apart of the Magnum Rider Community! Love how you accessorized your Cosmo X.
I Love This Bike!
Store owner replied: Way to accessorize, your ride is looking great! Thanks for being part of the Magnum Rider Community. Happy Riding!
I'm new to Ebikes but have used regular racing bikes and mountain bikes for many years. I am a very fit 68 year old male. However, with age, I am starting to slow down and wanted some assistance in my bike riding. I researched many brands and models. I made the decision to stay away from mail order bikes as I read of many instances of bikes received missing parts or damaged through shipment. My local bike dealer had 3 Magnum S bikes and several other brands. The Magnum bike had more standard features that were optional items on the other brands. The Magnum also appeared to be built better and had a more powerful motor and battery. The next day the dealer only had one Magnum S left. This bike had a paint flaw on the down tube so after negotiation between myself, the dealer, and Magnum I was able to purchase the Magnum S for a $200 discount applied to the price point. I added a handle bar mount bottle cage and a different more cushy seat. The bike performs well and meets every need I have. I checked the accessories page on the web sight and noted there are no parts such as inner tubes, tires, batteries, controllers, etc. that fit the Magnum S. I then Emailed Magnum about this and they responded the same day and stated: "Due to the pandemics effect on the supply chain, we are still experiencing delays in receiving bike parts to our location in Salt Lake City, UT. Unfortunately, it could be anywhere from 3-6 months, but we are going to be restocking it." Because of the maker not having something as critical as batteries for this bike and other items like inner tubes, tires, and electrical components I cannot give this bike the 5-star rating it deserves. Fabulous bike with questionable support. Hopefully, I won't have to replace any of the out of stock items soon.
Excellent riding bike! I'm very happy with it and would recommend it.
Excellent bikes, easy to put together. We love them and ride every day.
The battery arrived in timely fashion but it is not holding a charge. The old battery would only go down one bar on my daily commute to work and back. This new one drops down to where I have only one bar remaining. I tried calling your company and was told to file on line. I am very confused seeing as how I just received the battery
Perfect easy to install quick service thanks again
This eBike is so much easier for my wife to use. Much lighter and easier to get on and off the bike. She is a happy camper!
worked perfectly and showed up fast
Not as nice as my Metro+
They displayed his self is very small as are the numbers
Had the display for my Magnum Cosmopolitan ebike in stock. Quick shipment, greta price and fast delivery. Thanks Magnum
Excellent, fast service. New battery brought my 10 year old magnum Cosmopolitan ebike back to it's original glory. Thanks, Eric
I have not received the bike yet. I was told bike shop where it was shipped to will contact me when it is ready for pickup; but nobody contacted me. I do not know when/if I will receive my bike.
My wife is happy now that she can get back to riding her bike and have control and information that she can see!
Flawless transaction
Send a bike that isn’t damaged.
The batteries work great. Just wish the weren't so expensive.
Great shopping experience
My cosmo s are about three years old. I don’t know why you didn’t put stainless spokes. Mine are all rusted and have been inside most of the time. Also I have two bicycles
Great bikes, I now have 4
I’m grateful for Krysta and Magnum. I’m back riding.
Direct replacement, easy swap except the cord was about 2 inches shorter than the old one and had reposition inward toward bend in handlebars and rearrange feed wiring. ALMOST too short
We needed a replacement Speedometer for our Cosmos E Bike. This replacement was a perfect fit. Delivery was as predicted. Pleased with the transaction.

Great help getting the right part.
Incredibly cheap!!
Better than expected. Ride it almost everyday. Had to buy two more to ride with the family. Will purchase a couple more soon.
Love our new bikes. Comfortable ride and battery life is great

Is the Magnum Cosmo 2.0 T (CPO) a good e-bike for daily commuting?
Yes. The Cosmo 2.0 T (Certified Pre-Owned) is well suited for daily commuting because it combines a light low-step frame for easy mounting, a 500 watt motor with a torque sensor for smooth, responsive pedal assist, and a fully integrated 15Ah battery that stores substantial energy without bulky racks. Those features produce reliable acceleration from stops, comfortable mounting in urban settings, and clean aesthetics that fit city use. This model is ideal for active adults who want independent, practical transportation and frequent riders who value an enjoyable, consistent ride. As a CPO bike it has been inspected and reconditioned for safety and function, but range and top performance depend on assist level, terrain, and rider weight, so expect real-world range to vary with conditions.
How does the Cosmo 2.0 T (CPO) compare to similar e-bikes in build quality and reliability?
The Cosmo 2.0 T (CPO) compares very favorably on build quality and reliability. It uses UL certified components and premium parts such as a torque-sensing 500W motor and quality drivetrain elements, and it was designed and tested in Salt Lake City to meet real-world durability demands. The integrated 15Ah battery and integrated display reduce exposed wiring and stress points, improving long-term reliability. This makes it a strong choice for buyers who prioritize long-haul performance and fewer service visits. As a certified pre-owned unit it receives inspection and reconditioning to maintain standards, though buyers should note a CPO bike may show minor cosmetic wear compared with a new model.
Will the Cosmo 2.0 T (CPO) handle steep hills and heavier riders?
Yes, in most typical urban and suburban situations the Cosmo 2.0 T (CPO) will handle steep hills and heavier riders effectively. The 500 watt motor delivers robust assist power and the torque sensor provides proportionate pedal assistance so the motor responds directly to rider effort on climbs. The 48V 15Ah battery (approximately 720Wh) supplies sustained power for repeated hill climbs. This bike benefits riders who face hilly commutes or who carry extra weight from cargo or passengers. If you regularly tackle very long, steep grades or expect exceptional payloads, consider models with higher power ratings or check the bike's gross vehicle weight rating for your specific needs.
How long will the Cosmo 2.0 T (CPO) battery last between charges and over time?
Typical range per charge is variable but you can expect roughly 25 to 65 miles depending on assist level, rider weight, terrain, and riding style. The Cosmo 2.0 T uses a fully integrated 15Ah battery; paired with a 48V system this equates to around 720 watt-hours of capacity, which supports substantial daily use. Over time, modern lithium-ion e-bike batteries generally retain useful capacity for several hundred charge cycles; many riders see 3 to 5 years of service with normal charging patterns before noticeable capacity loss. This is a good fit for commuters and recreational riders who want predictable daily range. Actual results will vary with charging habits, storage conditions, and climate.
Is maintenance and servicing straightforward for a Cosmo 2.0 T (CPO)?
Yes. Maintenance and servicing for the Cosmo 2.0 T (Certified Pre-Owned) are straightforward because Magnum Bikes Online supports US-based service and a nationwide dealer network, and the bike uses widely serviceable components like torque-sensing motor systems and common drivetrains. The integrated battery and display simplify wiring and reduce exposed parts that require attention, while hydraulic brakes and quality components lower routine adjustment frequency. Certified pre-owned units are inspected and reconditioned before delivery, but owners should plan standard maintenance such as periodic brake bleed/checks, tire and drivetrain care, and annual tune-ups. This setup benefits riders who want accessible support and predictable upkeep; extremely specialized electrical repairs may still require a qualified e-bike technician.
