The Cyrusher Trax 2.0 is a full suspension fat tire e-bike with a step thru frame: a 750W Bafang hub motor with 95 N.m in the rear wheel, a torque sensor that matches the assist to how hard you pedal, and a 52V 20Ah battery, 1040Wh, sealed inside the down tube. Cyrusher rates it at 28 MPH and up to 75 miles.
A four bar rear linkage with a DNM air shock and a dual crown fork with 60mm of travel carry it over roots, ruts and curbs on 26 x 4 Kenda puncture resistant tires. Tektro four piston hydraulic brakes stop it, and a Shimano 9 speed covers the climbs. It weighs 87 lb and carries 350 lb.
The frame steps through at 20.5 inches, so getting on in work clothes or with a loaded rack is a step, not a swing. One size fits riders 5'7" to 6'6". Want the same bike with a step over frame? That is the Ranger 2.0.
Built to be lived with
A 6061 aluminium step thru frame with the battery inside, a four bar rear linkage on a DNM air shock, a dual crown fork with lockout, a 170mm 52T forged crank on a KMC chain and 12 gauge stainless spokes. Kenda 26 x 4 tires on alloy rims.
A 3.7 inch colour display, thumb throttle, LED headlight with horn, rear light with turn signals, kickstand and sport saddle on a 33.9mm post all come on the bike. Certified to UL 2849 and UL 2271. Frame, motor and controller are covered for two years, battery and parts for one.
The Trax 2.0 hangs its rear wheel on a four bar linkage with a DNM air shock, 165 by 28mm, tucked under the seat. Up front is a hydraulic dual crown fork with 60mm of travel and a lockout for pavement. Together they keep both 26 x 4 Kenda tires on the ground over roots, ruts and curbs instead of bouncing you off the saddle.
The frame is 6061 aluminium with the 52V battery hidden inside the down tube, and it steps through at 20.5 inches. Cyrusher fits it to riders from 5'7" to 6'6" on one size, with the saddle adjusting from 35.4 to 38.9 inches. The whole bike is rated to carry 350 lb.

The rear hub is a 52V 750W Bafang, and Cyrusher puts its peak torque at 95 N.m. A torque sensor reads how hard you press on the pedals and adds power in proportion, so the bike feels like your own legs on a good day instead of a switch that is either on or off. A thumb throttle is there when you want to stop pedalling.
Five assist levels top out at 28 MPH. The 52V 20Ah battery charges in 5 to 7 hours on the 52V 3A charger and is rated for 800 cycles. Cyrusher sells it as Class 2 or 3, so where you can ride at the top end depends on your local rules.

Cyrusher quotes up to 75 miles from the 52V 20Ah, 1040Wh battery, and that is a best case pedal assist figure. Rider weight, hills, headwind, cold weather, tire pressure and how much throttle you use all bring it down. Cyrusher suggests a low assist level while you learn the bike and your routes.
Cyrusher lists the Trax 2.0 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.
They are the same bike in two frames. The Trax 2.0 is the step thru, 20.5 inches over the frame, for riders 5'7" to 6'6". The Ranger 2.0 is the step over on the same 750W Bafang motor, 52V 20Ah battery, Tektro brakes and Shimano 9 speed. Both weigh 87 lb and carry 350 lb.
One size. Cyrusher fits it to riders from 5'7" to 6'6". The saddle sets from 35.4 to 38.9 inches off the ground, the handlebar sits 45.5 inches up, the wheelbase is 49.2 inches and the bike is 76.9 inches long. Standover is 20.5 inches because the frame steps through.
Mostly. You fit the front wheel and tighten its axle, thread the left and right pedals on with a 15mm wrench, set the handlebar in the stem and drop the saddle into its quick release post, then check every bolt. Cyrusher recommends a bike mechanic checks your work. Fenders and a rear rack are not included.
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.
