Cyrusher Quest Review: Serious Climbing Torque Off-Road for $2,599
A $2,599 fat-tire off-roader with serious low-end grunt and a big battery, best for riders who actually seek out the hard stuff.
If you ride real off-road, meaning steep fire roads, loose climbs, and rough terrain where a weaker bike would stall, the Cyrusher Quest has the muscle to keep going. It uses a putting out a big , and that's the number that matters when you're grinding up a grade with the trail fighting back. Our Genius Score lands it at 85 out of 100, and most of that comes down to how much capable, well-built bike you get for the money.
It's a bike, so pedal assist carries you up to 28 mph, and a twist means you can ride without pedaling at all. That combination helps when you're pulling away from a stop on a hill or you just want to cruise. The trade-off is where you're allowed to ride it, since a 28 mph Class 3 bike is restricted on some bike paths and multi-use trails, so it pays to check your local rules before you count on it everywhere.
Pros & cons
What we like
- A delivering , which is what actually gets you up steep, loose climbs
- A large 960Wh that backs up a claimed range of 50 to 80 miles
- A twist plus pedal assist to 28 mph, so you can pedal hard or just cruise
- Excellent value for the capability: at $2,599 you're getting a lot of off-road bike per dollar
- Strong stopping hardware with 4-piston on big 203mm discs
Worth weighing
- At 104.2 lb it's heavy even by fat-tire standards, so loading it onto a rack or carrying it upstairs is a two-person job
- As a bike with a throttle, its 28 mph speed keeps it off some bike paths and multi-use trails that cap or ban that class
Key specs
The motor & power
The heart of this bike is a Bafang M620 , and that placement earns its keep off-road. Because the power feeds through the same gears you're already shifting, you can pick a low gear and keep a steep, technical climb alive instead of losing it.
It's rated at 1000W with a big . On a loose or steep climb where momentum dies fast, that much pull is the difference between crawling up under control and stalling out.
One gap worth naming: Cyrusher doesn't list a for this motor. That's not a red flag, it just means the 1000W steady rating and the torque number are what you should judge it on, and both are strong for the price.
Range & battery
The 960Wh pack here is a big one, built from a 48V, 20Ah . More capacity means more room to run a hungry mid-drive hard without watching the gauge every mile, which is what you want on a bike meant for long, rough days out.
Cyrusher quotes 50 to 80 miles of . Treat the 80 as a best-case number from easy, flat riding. On real off-road terrain, with climbs, soft ground, and time spent on the throttle, plan closer to the bottom of that range, and think of anything above it as a bonus.
The honest takeaway is that the range window is wide because off-road riding is so variable. Even the low end gives you a solid day of trail time between charges.
Ride & components
Stopping power gets real attention here, and on a heavy, fast bike that's the right call. The Starunion 4-piston clamp onto large 203mm rotors front and rear, so you've got the bite to haul this thing down from speed or hold it back on a steep descent.
Shifting comes from a 9-speed Shimano drivetrain, which is a sensible, no-drama setup that gives you the gear range to pair with the motor on climbs. The 20-by-4-inch Kenda fat tires are puncture-resistant and give you a big contact patch for grip and float over loose or soft ground.
Then there's the weight. At 104.2 pounds this is a genuinely heavy bike, well past the 70 to 80 pounds that's normal for fat-tire models. The upside of all that mass is capacity: it's rated to carry , so a big rider plus a full load of gear is no problem.
Price & value
At $2,599, the Quest is priced well for what it can actually do. You're getting a torquey mid-drive, a large battery, 4-piston brakes on big rotors, and a high payload, which is a genuinely capable off-road package rather than a budget bike dressed up as one.
That's why value is the strongest part of its story. Against its peers, few bikes give you this much climbing power and battery at this price, so the money is going into the parts that matter for hard riding.
Most fat-tire e-bikes at this $2,599 price lean on a hub motor. The Quest gives you a Bafang mid-drive and 160 Nm for that same money, so when you shop it against rivals, weigh how much of your riding is real climbing, because that's exactly where the extra you're paying for shows up.
Who it's for
The climb-chaser
If your rides involve steep fire roads, loose hills, and terrain where lesser bikes give up, this is an easy pick. The mid-drive is built to grind up grades under load without stalling, and the big battery means you're not cutting the day short.
The load hauler
If you're a larger rider, or you pack a lot of gear for backcountry days, the rating gives you plenty of headroom. Add the for pulling that weight away from a dead stop on an incline and it stays easy to manage.
The cruise-without-pedaling rider
If you'd rather roll on the throttle than pedal every mile, the Quest is happy to do that, and it'll still take you to 28 mph on pedal assist when you do want to work. Between the two you can dial the effort up or down to match the terrain in front of you.
The bike-path commuter
If most of your miles are on paved multi-use paths, check the rules before buying. This is a bike with a 28 mph top speed and a throttle, and plenty of paths restrict or outright ban that class, so a machine built to attack trails may be more than those routes allow.
