The Compact bike has a long history in urban cycling lore. Originally designed for apartment dwellers, it took up less footprint in a foyer or hallway. But the real advantage is that there is no better bike for the city than a smaller wheeled bike. But why?

Physics is the answer! Unlike country riding - which is pretty much what every bike sold in North America is designed for - city riding involves two constants. The first is endless stops and interruptions. Stop signs. Red lights. Pedestrians not looking both ways before they cross the street. Riding in the city means you stop-and-go a lot and a small wheel has one major thing going for it: massive acceleration! A small wheel simply moves more revolutions per pedal stroke than a larger wheel. That means it reaches top speed quickly, and that makes you surprisingly fast. The second truth about riding in the city is that you rarely ride in a straight line. Cities are made up of constant 90 degree corners which require a bike with sharp and quick handling. And, the smaller the wheel, the better the cornering! 

The Cube Fold Sport Hybrid takes this long history and adds a powerful Bosch motor, a very clever handlebar that twists so it takes up less space in your hallway, and even further, folds to a transportable size! The Bosch motor reads your pedalling torque, pedalling revolutions, and wheel revolutions and constantly adjusts the power output to your needs. If you go up a hill, it knows and cranks up the power. When you get to the top of hill it powers back and continues to hum in the background. If you want more of this mind-reading power, you can crank the system up for more assistance too. It's quite sensational!

The rest of the bike is a story of smart engineering. An easy step-through frame that is unisex and designed for all riders. Hydraulic disc brakes to ensure intuitive yet powerful speed control. The highest level of puncture protection, and, finally a German-made lighting system that keeps the street (and yourself) visible.

How does a Cube compare to other e-bikes?

It's German! And, that means a lot. Germany is home to largest e-bike market in the world and also the highest regulations. This regulatory environment produces some of the best products out there since each brand competes with other brands for the highest level of safety. These regulations, known as the Straßenverkehrszulassungsordnung (try saying that three times fast!) cover everything from the nature of dynamo or electric lighting beams (and how they are not permitted to blind oncoming traffic) to the quality of everything from the kickstand to the rear racks. Built in Germany, Cube thus has access to tons of German parts that are made-in-Germany and are not easily available in China - where most e-bikes are made. Finally, there's just something ephemeral about the deep experience and maturity that is built into a Cube bike. Where so many North American brands are still figuring out how to build e-bikes, Cube has that all figured out and leads from the front. 

Why Bosch as the motor/battery system?

Bosch has been supplying the automotive industry for over 100 years and when they entered the e-bike market in the early 2000s they did so with a commitment to carrying over their extensive experience and focus on high standards of quality and reliability. As evidence of this Bosch was the first e-bike brand to ensure all of its motors, batteries and chargers meet UL 2849, an international e-bike safety standard. 

Bosch also draws on its automotive experience to create and maintain a massive network of highly trained dealers and service centres. This means you won’t struggle to find service for your bike whether that's with us or in another city around the world. 

Due to the high quality of the motor/battery systems and the massive network of service centres, investing in a Bosch system will save you time and money on maintenance and repairs over the life of the bike. Bosch also offers a spare parts guarantee, meaning they are committed to producing replacement parts, even for their discontinued systems, which means a longer life for your bike!

Does the battery lock to the bike?

Yep. That’s one expensive chunk of Lithium Ion. Frame-mounted batteries lock on to the down-tube and only you can remove them with the key provided. Internal frame batteries are built into the bike, so no need to worry!

How long does it take to charge the battery?

It takes about five hours to charge a single battery from flat to full. The batteries don't have memory so there is no problem if you only charge the battery a little bit, halfway, or whatever. You’ll get over 1000 complete charges, which is typically 5+ years of use before a replacement is required.

Is the unit serviceable?

You bet it is. For years the e-assist market was dominated by small fly-by-night companies with good ideas and no balance sheet. The consumer took all the risk and were often left with technical assistance phone numbers that no longer worked. Cube partner with Bosch, a huge player in the e-bike market – and they are sophisticated, which means they are updatable, diagnosable, and if something does break, fundamentally repairable.

What's the lifetime on the battery?

On average you will get about 18,000-20,000 miles from the battery before it needs to be replaced.

This is expensive! Will it get stolen?

Estimates are that over 90% of bicycle theft is tied to cash-for-drugs (unfortunately) and most bike losses are due to inferior or cheap locks. Make sure you buy a good ABUS U-lock or a chain and your bike will be safe. 

What’s the warranty?

For the original owner, Cube offers a two-year warranty for manufacturer defects on frame and fork, five years for frame / swingarm breakage, and two years on the battery. Does not include wear and tear.

Very good speakers
Size: Pair
The r51ms are used to compliment my klipsch rp500m speakers and a 12 inch subwoofer in a large living room. By placing the r51m speakers to the outside walls , and the rp500m speakers to the interior, closer to the amplifier, and with the subwoofer set on deep bass only at just enough volume to barely compliment the sound, the large living room is more than sufficiently covered with at least true high fi quality sound, if not true budget audiophile sound. My entire 2.1 system is all klipsch. That's how I want it. I am using them with a high powered tube amplifier, so presence and clarity is awesome. Placement is critical. I was initially disappointed until I switched the r51ms to the spread to the outside walls position, and the rp500ms to the interior, closer to the amplifier. The difference was remarkable. The 2 different klipsch speakers, ie one a rp and the other a r series blend together perfectly with no clash whatsoever because of somewhat more refined sound on the rp500m speakers. The rp500m speakers do sound higher end , but they are supposed to, but with the speakers as outer r51m and inner rp500m, and the klipsch subwoofer at deep bass with just a touch of volume the result is sound of such quality that I can honestly say I can be content and satisfied with it. I can say my system is complete, and no further improvement, upgrades are needed. Tower speakers as primaries are not necessary because of the high quality of sound and the high sensitivity of the 4 klipsch bookshelf speakers and klipsch subwoofer. This saves me money during this rapid inflation period of time. I could easily say that what I have sounds more than good enough to be satisfied and content with without any desire to upgrade further at this point. Shipping speed was excellent via Amazon itself, and the box and speakers arrived in handled with care and new condition. I am not disappointed at all now that the r51m speakers are the outside speakers, spread apart from corner wall to wall to compliment the interior placements of my rp500m speakers by klipsch. Im all klipsch here and I love it. 5 stars categorically. As previously stated, I see no need for primary tower speakers, even in a large living room, and that equals high quality sound and savings of money at the same time. I recommend these speakers. They do more than just do sound quality wise.

Great Sound
Size: Pair
Great things sometimes come in little packages. Powerhouse sound with virtually no input at all. Tight, crisp, and well-made as usual from Klipsch. If you are looking for a powerhouse monitor these are what you want.

Great starter speakers - for the right price.
Size: Pair
A good all-around pair of starter speakers if you're planning on using them as standalones. These will have zero trouble filling a small to medium sized space with rich and detailed sound at low to mid volumes. The bass is adequate for their size. They're not going to knock your socks off on more thumpy genres. I would imagine pairing them with a subwoofer would make quite the difference but for rock and some synth pop, they're pretty sweet. Plus the copper woofers look very striking without the faceplates. That said, I say these are best suited at low to mid volumes because cranked, the higher frequencies can be awfully fatiguing coming out of these speakers. I would not pay anywhere close to the $349 MSRP for these (you can probably find a pair of far superior RP-600Ms for around that price nowadays). Around $150 seems like a sweet spot for the R-51Ms, but the Sony SSCS5s and Fluance Signature bookshelfs are very comparable, if not better sounding for around the same price. Still, these will probably more than satisfactory if you're not expecting to be blown away by them. UPDATE 5/20/25: Can confirm that the subwoofer made a big difference. I was going to retire these since I replaced them with some bigger floor speakers on my main setup but I decided to try them out in place of the factory speakers on the Klipsch ProMedia 2.1 I have hooked up to my computer. Not only does the onboard amp seem to drive them okay at not-insane levels of volume - they sound really sweet paired with the 6.5-inch subwoofer. While I won't change my rating, I do highly recommend getting a sub along with these speakers.
