The Community Impact:
✓ Over half of those 10 bikes now reviewed on the channel
✓ Manufacturers took notice of viewer engagement
✓ Comments, likes, and shares drove this content
✓ 30,000+ subscribers made this possible
This review exists because you asked for it, engaged with content, and built a community around honest e-bike reviews.
FIRST IMPRESSIONS: UNBOXING & BUILD QUALITY
The Masterpiece Arrives
Opening the box reveals something immediately different. This isn’t another generic e-bike. The attention to detail starts before you even touch the bike.
What Makes It Special:
Premium Packaging:
✓ Master key with ID card for your specific unit
✓ Serial number documentation
✓ Meticulous assembly from Ristretto’s team
✓ Personal touch in every unit
“Ristretto takes a lot of pride in building and delivering these bikes to you. Every single unit is meticulously put together.”
The Frame: Art Meets Engineering
“Take it from me, there’s not a single e-bike on the market that looks like this one.”
The Ristretto 512’s frame is genuinely unique:
Design Highlights:
✓ Classic retro motorcycle aesthetic
✓ No other e-bike shares this design language
✓ Beautiful and functional geometry
✓ Premium paint options (four colors available)
Frame Options:
- Black Mamba (tested configuration)
- Beige/Cream (gorgeous but chips easily)
- Additional custom colors available
Paint Quality Note:
The beige paint, while stunning, chips relatively easily. Battery installation can scratch the frame if you’re not careful. Consider black for durability or beige for aesthetics with care.
Weight & Dimensions: Built Like a Tank
Specifications:
- Bike Weight: 88 lbs (without battery)
- Total Weight: 110 lbs (with 52V battery)
- Weight Capacity: 325 lbs
- Frame Material: High-grade steel construction
Why Heavy is Good:
“That’s pretty hefty, but this will make it super stable at speeds.”
The substantial weight provides:
✓ Rock-solid stability at 40+ mph
✓ Planted feeling in corners
✓ Confidence-inspiring handling
✓ No nervous wobbles or vibrations
Size Options: 20″ vs 24″ Wheels
Ristretto offers two configurations:
20-Inch Wheels (Tested):
✓ Best for riders under 5’10”
✓ Lower seat height (easier to swing leg over)
✓ Lighter wheels
✓ Faster acceleration
✓ Maximum torque delivery
✓ Most “flickable” handling
24-Inch Wheels:
✓ Best for riders near 6 feet or taller
✓ Higher seat height (comfortable for tall riders)
✓ Higher potential top speed
✓ Better for sustained high-speed cruising
Recommendation: Unless you’re 6’+ and prioritize top speed over acceleration, the 20-inch setup delivers the most fun, torquey experience.
Rider Fit (5’9″ Reference):
“Nice, comfortable. I can reach the ground flat-footed, no problem.”
The adjustable handlebars move toward or away from you, accommodating various rider preferences and sizes.
CONTACT POINTS: THE GOOD, BAD & UPGRADEABLE
What You’ll Touch Every Ride
The Grips: Perfect (10/10)
“The grips are perfect. Lock-on grips, super nice soft rubber compound. It sticks to my gloves. They are perfect grips.”
Specifications:
- Type: Lock-on design (easy replacement if needed)
- Material: Super soft rubber compound
- Grip: Excellent adhesion to gloves
- Quality: Would never replace unless worn out
The Seat: Good But Upgradeable (7/10)
“The seat is okay. I probably give it like a 7 out of 10. It’s not the most cushy seat out there. It’s very sporty.”
Assessment:
≈ Low-profile design (keeps standover height manageable)
≈ Decent padding for short-to-medium rides
≈ Firm, sporty feel (not plush)
≈ Fine for the price point
The Good News:
“They do make a thicker one on their website, so you can order one and upgrade it.”
Ristretto now offers cushier seat upgrades specifically designed for longer, more comfortable rides.
The Pedals: Major Weakness (3/10)
“If there’s one thing I’d replace right away on this bike, it’s definitely the pedals.”
The Honest Truth:
✗ Cheapest plastic pedals encountered
✗ Don’t match the premium quality of everything else
✗ Only component that feels budget
“Everything on this bike feels like such high quality. And then you get some plastic pedals.”
Why This Matters:
For a $4,000 bike with motorcycle-grade quality everywhere else, cheap plastic pedals feel like a significant oversight.
Easy Fix ($20-30):
- Replace with metal platform pedals
- Add metal pins for grip
- Upgrade to RedShift Arcite pedals (LED-equipped, premium option)
“That’s a super easy upgrade. It’s like 20, 30 bucks on Amazon.”
The Bottom Line:
The pedals are the ONLY component that doesn’t match the bike’s premium nature. Budget $30 for an immediate upgrade.
Handlebars: Goldilocks Design
“The bars you get with the 512 are kind of in between BMX bars and mountain bike bars.”
Design Philosophy:
- Not flat like mountain bike bars
- Not super tall like BMX bars
- Middle ground for comfort + control
- Center mounting area for accessories
Accessories That Fit:
✓ Phone mounts
✓ Additional lights
✓ Action cameras
✓ GPS units
Stem: Adjustable Reach
The stem isn’t super short or super long, providing:
- Opportunity to swap for shorter stem (bars closer)
- Option to install longer stem (extended reach)
- Stock setup works for most riders
Controls: Well-Designed Layout
Right Side:
- Super soft rubber lock-on grip
- Thumb throttle
- Hydraulic Tectro brake lever
Left Side:
- Matching lock-on grip
- Master controller (horn, lights, turn signals)
- Remote for computer display
Power Button Functions:
- Cycles through different modes
- Arrow buttons adjust power levels 1-3
- Clean, intuitive interface
THE HEART OF THE BEAST: CYC X1 PRO GEN 4 MID-DRIVE
Why Mid-Drive Matters
“Mid-drive motors are known for their instant torque, and this one is no exception.”
The CYC X1 Pro Gen 4 is the most compact mid-drive system delivering an insane power-to-size-weight ratio. Here’s why this motor choice is brilliant:
Advantages Over Hub Motors:
✓ Incredible torque multiplication through bike’s gears
✓ Weight centered in frame (superior handling)
✓ More efficient power delivery
✓ Uses bike’s existing drivetrain
✓ Better hill-climbing ability
✓ More natural bike feel
Power Output: 6,000 Watts Peak
Maximum Power: 6,000W
Continuous Power: ~3,000-4,000W (estimated)
Torque: Absolutely brutal (specific numbers not published)
What 6,000W Feels Like:
“Oh my god. They told me this bike could accelerate fast. Jesus.”
This isn’t marketing exaggeration. The power delivery is genuinely shocking, even for experienced e-bike riders.
The Gearbox Advantage
Unlike direct-drive systems, the Ristretto 512 uses:
- Dual-chain setup
- Drive chain connected to motor
- Freewheel engagement system
- Fully guarded chains (carbon fiber guards)
- Chain tensioner system
Benefits:
✓ Quieter operation than direct drive
✓ Smoother power delivery
✓ Reduced mechanical noise
✓ Motor disengages when coasting (efficient)
“There’s no derailleur or anything back here to clack around and cause extra noise. All you have is a roller here that ensures that the chain stays on.”
Drivetrain Design: Simple and Effective
What You DON’T Have:
✗ No derailleur (single-speed setup)
✗ No gear shifting complexity
✗ No chain slap or noise
What You DO Have:
✓ Single gear optimized for motor
✓ Chain roller to prevent derailment
✓ Full chain guards (safety + cleanliness)
✓ Carbon fiber guard aesthetics
Pedal Assist: Torque Sensor Technology
The bike features genuine torque sensing:
How It Works:
“This bike’s got a torque sensor on the pedals, right? So like the more I push, the faster it goes.”
Benefits:
✓ Natural, bike-like feel
✓ Power proportional to pedaling effort
✓ No power without pedaling force
✓ Ghost pedaling doesn’t activate motor
The Single-Gear Reality:
“The issue is with the torque sensor and only having one gear back there is as you get going faster, you kind of run out of gears really fast.”
At 15 mph: Pedaling becomes very fast
At 20+ mph: Essentially spinning without resistance
At 30+ mph: Ghost pedaling territory
The Honest Take:
“Obviously, you’re only going to pedal this thing when you’re going slow, right? Maybe when you’re just getting going or maybe when you’re crossing the road just to show people you’re on a bike and not a motorcycle.”
This is a throttle bike with pedals for legality, not a pedal-assist bike with throttle backup. And that’s perfectly fine for what it is.
REAL-WORLD PERFORMANCE TESTING
Hill Climb Test: 32 MPH UPHILL
The Standard Test:
- Starting point: Fire hydrant marker
- Mode: Race Mode, Level 3 (maximum power)
- Method: Throttle only (no pedaling)
- Battery: Fully charged
The Results:
Starting speed: 32 mph (before hill begins)
Uphill speed: 32 mph MAINTAINED
Climbing ability: Best ever tested
“Holy. Okay, I’ve ridden a lot of really good bikes. I think this takes the cake as far as climbing ability. The torque with this thing is absolutely insane.”
What This Means:
Most e-bikes lose significant speed on hills. The Ristretto 512 maintains 32 mph on grades that would slow competitors to 15-20 mph. This is genuine performance.
Acceleration Test: 20 MPH Before Driveway
Standard Test:
- Starting point: Lamp post
- Target: Driveway pull-out ahead
- Goal: Reach 20 mph before driveway
- Fast bikes achieve this easily
The Results:
“20 already. Oh man, my GPS is lagging a little bit, but I was hitting like 25 miles an hour before that driveway pull out. This bike is insane.”
Achievement: 25 mph before marker
Acceleration: Exceptionally quick
Power Delivery: Instant and brutal
The acceleration genuinely catches you off guard, even when you’re expecting it.
Top Speed Test: 38.5 MPH (52V Battery)
Testing Conditions:
- Location: Test Drive Island (flat, safe, legal testing area)
- Battery: 52V Catalina fully charged
- Rider Weight: 190 lbs + gear (~195 lbs total)
- Mode: Race Mode Level 3
- Method: Full throttle
Claimed vs Actual:
Manufacturer Claim: 40 mph
Actual GPS Speed: 38.5 mph
Difference: 1.5 mph under claim
The Honest Assessment:
“So, you could probably hit 40 miles an hour with a smaller human on it. I mean, I’m 190 lbs, maybe 195 with all the gear on.”
Factors Affecting Top Speed:
- Rider weight (lighter = faster)
- Battery charge state (tested after multiple runs)
- Voltage sag from previous tests
- Wind conditions
- Rider position (tucked vs upright)
With Fresh Battery + Lighter Rider:
Expected top speed: 40+ mph achievable
The Verdict:
“I’m not choked about that at all.”
38.5 mph is impressive, and 40 mph is likely achievable under ideal conditions. This isn’t false advertising—it’s realistic variation.
Brake Test: Stopping Power Excellence
The Setup:
- Starting point: Standard marker
- Distance to brake point: ~20 feet
- Target speed: 28 mph (standard e-bike top speed)
- Method: Full brake application
The Hardware:
Front: 4-piston Tectro hydraulic caliper + 203mm rotor
Rear: 4-piston Tectro hydraulic caliper + 180mm rotor
Why This Matters:
“Ristretto is not messing around here when it comes to stopping power.”
The Results:
Braking distance: Under test distance with room to spare
Control: Progressive, predictable
Feel: Confidence-inspiring
Power: More than adequate for the speed
“I still have another bike length to go, man.”
The bike stopped well before the target marker, demonstrating exceptional braking performance.
The Quality Difference:
“The difference between a $2,000 bike and a $4,000 bike is night and day. This is a masterpiece.”

✓ 203mm rotors front (maximum size for bikes)
✓ 180mm rotors rear (appropriately sized)
✓ Tectro brand (reliable, serviceable)
✓ Bleed ports for easy maintenance
✓ High-quality brake pads
Maintenance Note:
“These are Tectro brakes. They’re super easy to maintain. You’ve got a bleed port here. You can put your funnel in, get rid of any air bubbles that build up over time.”
Off-Road Capability: Surprisingly Good
Important Note:
“These are dual sport street tires. They’re not designed for off-road use, right?”
Despite street-focused tires:
“This thing is insane.”
Gravel Performance:
✓ Maintains traction surprisingly well
✓ Suspension absorbs bumps effectively
✓ Stable and composed
✓ More capable than expected
The Honest Approach:
“I’m being super careful in the corners. I don’t want to come up on anybody doing 30 miles an hour.”
With appropriate tires, this bike would be genuinely capable off-road. The suspension and frame can handle it—the street tires are the limiting factor.

“Like nothing. Really, really well done.”
The suspension absorbs impacts that would be jarring on budget bikes. The difference is immediately noticeable.
Off-Road Performance:
Even on gravel with street tires:
“This bike is just leaps and bounds higher quality than 90% of the bikes I review on the channel.”
The Quality Gap:
“The difference between a $2,000 bike and a $4,000 bike is night and day. And if you’re lucky enough or work hard enough to be able to afford it, you’re not going to be disappointed riding one of these.”

The Beautiful Simplicity:
- Remove 52V battery with key
- Slide in 72V battery (same mounting)
- Change voltage setting in app (52V → 72V)
- Done
“If you already own a Ristretto 512 with the 52V battery, installation is absurdly simple.”
No rewiring, no technical expertise, no voiding warranties. Just swap and ride.
Extra Parts Confusion:
The 72V battery ships with additional mounting plates and hardware, but:
“You don’t need them.”
For existing 512 owners, the batteries are identical in shape and mounting. The extra parts remain a mystery but don’t affect the simple installation.
72V Winter Performance Testing
Testing Conditions (Brutal):
- Temperature: Below freezing
- Rider weight: 245-250 lbs (winter gear)
- Battery: Fully charged (82.3V displayed)
- Gearing: Stock (not yet optimized)
Top Speed Results:
GPS-Verified Speed: 51-53 mph
Display Speed: Slightly higher (GPS more accurate)
Expected Summer Performance:
55-57 mph at normal 220-225 lb weight
58+ mph for riders under 200 lbs
60+ mph with gearing optimization
“For comparison, I expected 55-56 mph even in these conditions based on my experience with the CYC drive on other bikes.”
Factors Limiting Winter Speed:
- Cold battery chemistry (reduces output)
- Cold air density (increases drag)
- Possible speed limiting to protect drivetrain
- Heavy winter gear adding weight
Power Delivery Difference:
“Even on level 1 pedal assist, the throttle response is more aggressive. The torque delivery is smoother yet more powerful.”
The 72V system provides:
✓ More aggressive throttle response
✓ Smoother yet more powerful torque
✓ Higher sustained speeds
✓ Better acceleration at all speeds
72V Range Expectations
Conservative riding (20-25 mph):
40-50 miles realistic
Spirited riding (30-35 mph):
25-35 miles
Maximum performance (50+ mph):
15-20 miles
Real-World Example:
3-4 miles of high-speed testing:
Voltage drop: 82.3V → 77V
Assessment: Respectable efficiency for performance
The Trade-Off:
Less total capacity (20Ah vs 30Ah) but significantly higher voltage creates different performance characteristics. Choose based on priorities: range (52V) or speed (72V).

Level 3: “Okay, so I got 36 miles an hour here in level three.”
After factory reset to remove speed limiting:
“37, 38.5… So you could probably hit 40 miles an hour with a smaller human on it.”
Throttle Response: Premium Feel
What Separates Premium from Budget:
“How responsive is this throttle, right? Good throttles, especially the full twist throttles, you actually have a lot of control over the amount of power.”
Testing Throttle Precision:
Beginning of throttle travel: Very little power
Middle throttle: Proportional mid-range power
Full throttle: “Oh, it always catches me off guard how much freaking power this thing has.”
The Quality Difference:
“Really nice and it’s instant. Like there is zero lag between the time you push on the throttle and you get power.”

- Ristretto 512 to 72V: Swap battery, click button, done
Who Should Choose Which:
- Super73: Want proven ecosystem, prefer their aesthetic, don’t need max performance
- Ristretto 512: Prioritize power, speed, upgradability, classic design

The Onyx RCR is frequently compared to the 512:
Onyx Advantages:

Ristretto 512 vs Budget E-Bikes ($2,000 Range)
The Quality Gap:
“This bike is just leaps and bounds higher quality than 90% of the bikes I review on the channel.”
What You Lose at $2,000:
✗ Premium motor (budget hub motors common)
✗ Quality suspension (basic or none)
✗ Powerful brakes (often 2-piston, smaller rotors)
✗ Build quality (mass production, lower standards)
✗ Customization options (limited or none)
✗ Reliability (more likely to have issues)
What You Gain at $4,000:
✓ Premium CYC mid-drive motor
✓ Exceptional suspension (adjustable, premium)
✓ Top-tier brake system
✓ Motorcycle-grade build quality
✓ Extensive customization
✓ Proven reliability
The Value Question:
“Obviously if you can afford it… If you value quality and you want yourself a bike that’s going to last, right? That’s not going to wear out on you, look at something like this.”
Is the $2,000 premium worth it?
For performance enthusiasts: Absolutely yes
For casual riders: Probably not necessary
For those who can afford it: No regrets
WHO SHOULD BUY THE RISTRETTO 512?
Perfect For:
✓ Performance enthusiasts wanting 40-60 mph capability
✓ Riders who value classic retro motorcycle aesthetics

Not Ideal For:
✗ Riders prioritizing ultra-long range over performance (60+ miles needed)
✗ Those wanting the most advanced software (Segway integration better)
✗ Budget-conscious buyers under $3,000 budget
✗ People needing extreme off-road capability (not designed for that)
✗ Casual riders who won’t utilize the performance
✗ Those uncomfortable with high speeds (40-60 mph)

If this describes you, the Ristretto 512 is likely your perfect bike.
BUYING GUIDE: 52V vs 72V DECISION
Should You Buy 52V or 72V?
Buy 52V If:
✓ Budget is tight (~$4,000 limit)
✓ You prioritize range over top speed
✓ 38-40 mph is sufficient
✓ You want the longest possible battery life
✓ You might upgrade to 72V later (keep 52V as spare)
Buy 72V If:
✓ Budget allows (~$4,500+)
✓ You want maximum performance immediately
✓ 50-60 mph capability appeals to you
✓ You don’t need 40+ mile range
✓ You want the “complete” experience from day one
Our Recommendation:
“If you’re ordering a Ristretto 512 new, get the 72V battery from the beginning.”
Reasons:
- Avoid having unused 52V battery
- Get the performance the bike deserves
- Experience the bike at its full potential
- Better long-term satisfaction
Already Own 52V?
“The upgrade is absolutely worth it. The performance difference is substantial enough that it genuinely feels like a different bike.”
The 52V battery isn’t wasted though:
- Keep as spare for extended range (swap mid-ride)
- Use for casual city cruising (lighter, less power needed)
- Sell to offset 72V upgrade cost
Financing Considerations
At $4,000-5,000, financing options matter:
Ristretto Options:
- Check website for current financing
- Typical: 0% APR for 12-24 months (qualified buyers)
- Monthly payments: ~$166-$333 depending on term
Alternative Financing:
- PayPal Credit
- Affirm
- Credit card points/rewards
The Investment Perspective:
“This is a bike that’s going to last, right? That’s not going to wear out on you.”
Amortized over 5-10 years of ownership, the premium price becomes more reasonable. Especially compared to buying a $2,000 bike that needs replacing in 2-3 years.

The 72V Transformation:
“The 72V battery upgrade has arrived, and it transforms the Ristretto 512 from an impressive retro-styled e-bike into an absolute beast.”
What the upgrade means:

- More aggressive power delivery
- Genuinely competes with vehicles costing thousands more
- Maintains ease of customization
The Bottom Line:
“Would I buy it again? Absolutely. In fact, I’m already planning summer upgrades.”
This is the ultimate endorsement. After 500 miles of real-world riding, extensive testing, and comparing to countless other e-bikes, the verdict is clear:
The Ristretto 512 is one of the best $4,000 you can spend on two wheels if you value:
✓ Performance

It’s not perfect (those pedals!), but it’s as close to perfect as a performance e-bike gets in 2025.
Should You Buy It?
