The Cyrusher Rover Pro is a full suspension fat tire electric mountain bike with a step over frame: a 52V 750W rear hub motor with 95 N.m, a sensor you can switch between torque and speed modes, and a 52V 15Ah battery of EVE 21700 cells, 780Wh, sealed inside the down tube. Cyrusher rates it at 28 MPH and up to 62 miles.
A four link frame with an XR-3 AIR rear shock and a suspension fork with hydraulic lockout carry it over rock, sand and broken pavement on 26 x 4 fat tires. HD-E500 hydraulic disc brakes on 180mm rotors stop it and cut the motor, and a Shimano 7 speed covers the climbs. It weighs 80.5 lb and carries 350 lb.
A bright LED headlight, a smart display and a rear light with running, brake and turn signal functions all come on the bike. Want more battery and a torque sensor with four piston brakes? That is the Ranger 2.0.
Built to be lived with
A 6061 aluminium four link full suspension fat bike frame with the battery inside, an XR-3 AIR rear shock, a 26 inch suspension fork with hydraulic lockout, HD-E500 hydraulic discs with sintered pads, a Shimano 7 speed and 26 x 4 Chaoyang fat tires on 36 hole rims.
An LED headlight, smart display, integrated running, brake and turn signal lights, 700mm riser bar, memory foam saddle and adjustable kickstand all come on the bike. Frame, motor and controller are covered for two years, battery and parts for one.
The Rover Pro hangs its rear wheel on a four link frame with an XR-3 AIR shock, 210 by 32mm. Because it runs on air, you set it to your weight with a shock pump: firmer for support when you are loaded up, softer for comfort on washboard and roots. Up front, a 26 inch suspension fork takes the hits and locks out with a hydraulic lever when the road turns smooth.
Both ends roll on 26 x 4 Chaoyang fat tires on 36 hole rims, so sand, gravel and snow feel like a wide road. The frame is 6061 aluminium with the battery inside and a 29.9 inch standover. Cyrusher fits one size to riders from about 5'7" to 6'7" and rates the bike to carry 350 lb.

The rear hub is a 52V 750W brushless motor with 95 N.m of torque. In torque mode it reads how hard you press and adds power in proportion, which is what you want on a loose climb. In speed mode it gives steady support at the level you pick, which is what you want on the ride home. One switch on the bar changes it.
Five assist levels top out at 28 MPH. The 52V 15Ah battery charges in about 7 to 8 hours on the 58.8V 2A charger and is rated for 800 cycles. Cyrusher sells the Rover Pro as Class 2 or 3, so where you can ride at the top end depends on your local rules.

A left hand pad for power, lights, assist level, turn signals and the torque or speed switch.

52V 15Ah of EVE 21700 cells, 780Wh, sealed in the down tube behind a high brightness LED headlight.

Cyrusher quotes up to 62 miles from the 52V 15Ah, 780Wh battery, reached in their testing at a low assist level on favourable ground. Rider weight, terrain, cold, tire pressure and assist level all bring it down, and fat tires on sand or snow use more than pavement does.
Cyrusher lists the Rover Pro as Class 2 or 3, with 28 MPH reached in pedal assist level 5. In most US states that is legal on roads and many bike lanes, but paths and trails set their own limits. Check your state and local rules, especially where Class 3 bikes are kept off multi use paths.
Cyrusher says the Pro replaces the original Rover with a redesigned four link frame, an XR-3 AIR rear shock, a sensor you can switch between torque and speed modes, revised electronics, and a rear light with running, brake and turn signal functions built in.
Torque mode reads how hard you press on the pedals and adds power in proportion, so climbs and loose ground feel natural. Speed mode gives steady support at the assist level you pick once the pedals turn, which suits easy cruising. You switch between them on the bar.
One size. Cyrusher lists riders from 170 to 200 cm, about 5'7" to 6'7". The saddle sets from 35.6 to 41.3 inches, standover is 29.9 inches, the handlebar sits 45.3 inches up and is 27.6 inches wide, the wheelbase is 49 inches and the bike is 78 inches long, with 5.9 inches of ground clearance.
Cyrusher covers the frame, motor and controller for two years and the battery and other parts for one year against manufacturing defects, for the original owner, one replacement per part. Crashes, stunt riding, water damage, modifications and normal wear are excluded. We are an authorized dealer, so it applies.
