The exact bike I rode, when it's back

It pulled from a dead stop on the throttle and the big shocks soaked up bumps, but the seat sits too low to pedal at 6'1", and it was sold out on Oct 27, 2026. Read my Fahrbike Roadster 73 review.

Scroll sideways on a phone. Rated range is the maker's claim. A dash means I couldn't verify that number. Video = when my review went up on YouTube.
Every bike on this page is one I rode and filmed myself (2 bikes, videos from 2024 to 2025). Bikes I haven't ridden are left out. The top pick for each use is the bike with the highest AEB Score in that group that you can still buy. The score comes from the specs (range, motor, brakes and build, practicality) plus the current maker price, so it's the same yardstick for every bike. Specs come from the maker's listing, checked against what I saw on the ride. Prices are from my review data; tap through for the current price. More detail on how I test.
Straight from the downsides I hit in each review. If one of these is a dealbreaker for you, look at the next bike.
MACFOX X7: skip it if this bothers you: Less power on inclines than I wanted at about 200 lb Also: Headlight has its own power switch, separate from the display
Ailife X20B: skip it if this bothers you: Cramped pedaling for tall riders Also: Messy welds and cables
Squeeze the throttle on the Fahrbike Roadster 73 and it just goes. It pulled from a dead stop with no pedaling at all (Roadster 73 video, 4:12 to 4:20), and the oversized shocks front and rear soaked up the bumps (1:28 to 1:44). Then I tried to pedal it at 6’1” and it was almost comical, because the seat sits too low (1:54 to 2:16). That’s moto-style e-bikes in a nutshell. They look like little motorcycles, with a long bench seat, fat 20 inch tires and a big round headlight, they’re a blast on the throttle, and they’re easy to buy wrong. My e-bike types guide explains the category.
I’ve ridden two of the bikes on this page, the Roadster 73 and the MACFOX X7. I haven’t ridden the other two, the Fahrbike Roadster73 Plus and the Super73 Z Miami Core, and I’ve labeled them that way. Prices and stock below were checked on each maker’s site on Oct 27, 2026.
The Roadster 73 is the moto-style bike I rode the most. Beyond that throttle and suspension, the brakes still had plenty of stopping power after a few minutes at full throttle (5:11 to 5:33), and it has a halo-style LED headlight, an integrated tail light, a big seat and a rear rack (5:40 to 6:28). I got 42 miles out of it in winter at about 200 lb (3:57 to 4:02). I didn’t say on camera whether that was on throttle, pedal assist or a mix, so treat it as one cold-weather result, against Fahrbike’s claim of 35 to 60 miles.
It wasn’t perfect. The chain sat so close to the rear tire that it rubbed in some gears (6:37 to 7:09), and the tail light wire on my bike was frayed at the plug, which may have been a one-off (7:20 to 7:57). Fahrbike lists a 5’3” to 6’4” rider range, but at my height I had barely any leg extension (3:05 to 3:12) and said I’d probably just use the throttle (2:17 to 2:24).
The bigger catch is stock. It was $1,399 when I filmed (8:40 to 8:45). On Oct 27, 2026, Fahrbike listed the Orange and Blue versions at $899 and the Dark Green I tested at $1,399, against a $1,799 regular price, and all three were sold out. Fahrbike’s page points buyers to the Roadster73 Plus instead. It comes with a 24-month warranty and 15-day returns on unused bikes, with you paying return shipping and no restocking fee.
I haven’t ridden the Roadster73 Plus, so everything here is from Fahrbike. It was $899 in Dark Green and in stock on Oct 27, 2026, down from $1,999, with a 750W motor, a bigger 48V 20Ah battery, a Shimano 7-speed and hydraulic discs. What interests me is height. Fahrbike says the Plus is a good choice “especially for taller riders thanks to a seat riser accessory,” and that $89 riser says it only works on the Plus. If you’re my height and want to pedal, that riser is the reason to pick the Plus, but I can’t tell you how much it helps.
The MACFOX X7 is styled even more like a moped, with a long fixed seat (0:18 to 0:49) and foldable foot pegs on both sides (0:51 to 0:59). It has hydraulic brakes (2:16 to 2:24), a simple display with three assist levels, a thumb throttle, a front fork with no rear suspension, and fat tires I called 4.5 by 20 inches (X7 video, 2:24 to 5:32). The pegs are the main reason to choose it. I said a passenger would work as long as they don’t pedal (7:36 to 7:43), but the only rating I found from MACFOX is a 330 lb rider weight limit, so keep rider and passenger together under that.
At about 200 lb, I was disappointed on inclines (2:46 to 3:03) and wished it had more power, though I said that makes it ideal for a teenager who isn’t driving yet (9:11 to 9:29). It’s single speed (7:51 to 8:04), the cranks felt short at 6’1” (8:06 to 8:19), and some wires and the battery mount sit outside the frame (5:46 to 6:05). One conflict to flag: in the video I said it was limited to about 28 mph while calling it a 500W Class 2 bike (1:24 to 1:31). Class 2 stops at 20 mph, and MACFOX’s page lists 20 mph, so go by MACFOX.
On Oct 27, 2026, MACFOX listed the single-battery X7 at $1,599 and the dual-battery version at $2,098, both in stock, with other colors $100 more. MACFOX says it’s UL 2849 certified in the single-battery setup, and it carries a 2-year warranty and 15-day returns on unused bikes in original packaging.
I haven’t ridden or filmed the Super73 Z Miami, so this is Super73’s published information. It was $2,195 and available on Oct 27, 2026, and at 59 lb it’s the lightest bike here by a wide margin. It’s also built small, for riders 4’6” to 5’11” and, per Super73, 16 and older, with bikes paired to the app after Jan 1, 2025 locked to the Class 2 mode they ship in. It’s single speed with no suspension and Tektro mechanical disc brakes, which need cable adjustment as the pads wear. Returns are only on unopened bikes within 15 days, with a 15% restocking fee (Super73 returns). The warranty is one year on the frame and fork and two years or 500 cycles on the battery and electrical parts (Super73 warranty PDF).
If you shop used, know that in February 2025 the CPSC announced a recall of about 1,400 model year 2024 Z Miami SE and Z Adventure Core bikes because the brake caliper retaining pin can come loose. It covers the SE, not the Core sold now, but check any used bike against Super73’s recall page.
Specs are from each maker’s page. Each maker words its weight rating differently, so I’ve used its own label.

With weights from 59 to 87 lb, none of these is a bike you’ll want to carry up stairs.
The biggest thing to understand about moto-style bikes is that they’re throttle bikes that happen to have pedals. Both bikes I rode were cramped at 6’1”, and the X7 uses a cadence sensor (6:51 to 7:04), so the motor responds to whether you pedal, not how hard. The two Fahrbikes at least have gears. If you’re tall and want to pedal for real, the Plus with its riser is the only option here that addresses tall riders, and I haven’t tested it. Otherwise, a regular fat tire bike from my types guide will suit you better.
Brakes deserve the same honesty. These are heavy bikes on fat tires that reach speed quickly on throttle, so of everything on the spec sheet, the brakes are what I’d care about most. Both bikes I rode have hydraulic discs, as does the Plus per Fahrbike; the Super73 uses mechanical discs. For charging, Fahrbike lists 6 to 10 hours (I said “just a few hours” in my video without timing it, 8:01 to 8:15), MACFOX lists 5 to 6 and Super73 lists 5. Use the charger that came with the bike, and don’t leave a battery charging unattended overnight in a bedroom.
Moto-style bikes often get bought for teens, so check the rules first. Most states use three classes: Class 1 is pedal assist to 20 mph, Class 2 adds a throttle to 20 mph, and Class 3 is pedal assist to 28 mph. All four bikes here are listed at 750W or less. The X7 and Z Miami are Class 2, but Fahrbike lists the Roadster 73 as settable to Class 3, up to 28 mph, and that’s the setting that triggers age and helmet rules. In California, riders under 16 can’t operate a Class 3 and everyone under 18 must wear a helmet on any bicycle (California page). New York’s minimum age is 16 (New York page). If your teen is under 16, leave a multi-class bike in Class 1 or 2, and read my guide for parents, Class 2 vs Class 3 and e-bike laws by state.
I also rode the Ailife X20B (X20B video), but it’s no longer sold: Urban Drift’s product page returned “not found,” and the Amazon listing is gone. An April 2024 archive of its page listed a 1,000W motor and 30 mph, past the limits most states set for an e-bike. If it caught your eye, the MACFOX X7 is the moto-style bike I rode that you can buy today.
If you’ll ride on the throttle and want an in-stock Fahrbike, the Roadster73 Plus at $899 is the obvious path, knowing I haven’t ridden it. If you want pegs and a long seat and your rides are flat, the MACFOX X7 is the one I rode. If you’re under about 5’11” and want a name brand, the lightest bike here and a Class 2 lock, the Super73 Z Miami fits, again unridden by me. And if you want the exact Roadster 73 I rode, you’ll have to wait for it to come back in stock. Skip the category entirely if you’re tall and want to pedal, need a light bike, ride steep hills (see my hills guide), or need to carry a passenger often, in which case my passenger seat guide is the better start.
