The Cyrusher Quest is a mid drive, full suspension step through e-bike on fat tires: a Bafang M620 motor at the cranks, rated 1000W and 160 N.m with a torque sensor, and a 48V 20Ah battery, 960Wh, sealed inside the down tube. Cyrusher rates it at 28 MPH and 50 to 80 miles.
A DNM air fork with 160mm of travel, a DNM air rear shock and a DNM suspension seat post carry it over rough ground on 20 x 4 Kenda puncture resistant tires. Starunion four piston hydraulic brakes on 203mm rotors stop it, and because the motor drives through the Shimano 9 speed, the low gears multiply it on steep climbs. It weighs 104.2 lb and carries 440 lb.
The frame steps through at 15.5 inches and one size fits riders 5'1" to 6'2". Want full suspension on a step through with a hub motor instead? That is the Kommoda 3.0.
Built to be lived with
A 6061 aluminium step through frame with the battery inside, a DNM USD-8FAT air fork, a DNM air rear shock, a DNM suspension seat post, Starunion four piston brakes on 203mm rotors, a Shimano 9 speed with a KMC chain and 20 x 4 Kenda puncture resistant tires on alloy rims with 12 gauge stainless spokes.
A 1000 lumen LED headlight, Bafang colour display, throttle, kickstand and sport saddle come on the bike, with an air pump and assembly tool set in the box. Frame, motor and controller are covered for two years, battery and parts for one.
Cyrusher calls the Quest the first 20 inch step through e-bike with a mid drive and full suspension, and it takes the suspension further than most. A DNM USD-8FAT air fork gives 160mm of travel up front, a DNM air shock, 185 by 24mm, works the rear, and a DNM suspension seat post takes the last of it before it reaches you. Both air springs are set to your weight with a shock pump.
The frame is 6061 aluminium with the battery inside and steps through at just 15.5 inches, on 20 x 4 Kenda puncture resistant tires. The saddle sets from 33.7 to 41.3 inches, Cyrusher fits one size to riders 5'1" to 6'2", and rates the bike to carry 440 lb.

The Bafang M620 is a heavy duty mid drive with all metal gearing, rated by Cyrusher at 1000W and 160 N.m. It sits at the cranks and drives the rear wheel through the Shimano 9 speed, so shifting into a low gear gives it more leverage on a steep climb, and its torque sensor adds power as you press harder.
Five assist levels top out at 28 MPH, and a throttle is there when you want to stop pedalling. The 48V 20Ah battery charges in 4 to 5 hours on the 48V 4.5A charger and is rated for 800 cycles. Cyrusher sells the Quest as Class 2 or 3, so where you can ride at the top end depends on your local rules.

Cyrusher's spec table says 50 to 80 miles from the 48V 20Ah, 960Wh battery, and its own copy quotes up to 100 km elsewhere on the page, so plan on the lower end for mixed riding. A mid drive uses the gears, which helps on hills, but rider weight, cargo, cold and assist level all bring it down.
Cyrusher lists the Quest 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.
Both are full suspension step throughs on 20 x 4 fat tires. The Quest puts a Bafang M620 mid drive with 160 N.m at the cranks, driving through a 9 speed, with DNM air suspension and 4 piston brakes, at 104.2 lb. The Kommoda 3.0 uses a 750W rear hub, a 7 speed and a lower price, at 83 lb.
One size. Cyrusher lists riders from 5'1" to 6'2". The step is 15.5 inches, reach 17.9, top tube 24.8, the saddle sets from 33.7 to 41.3 inches, the wheelbase is 46.5 inches and the bike is 68.5 inches long.
Cyrusher ships the battery, the 48V 4.5A charger, an air pump and an assembly tool set in the box. You fit the front wheel, handlebar, pedals and saddle, set the fork and shock pressure for your weight, then check every bolt before the first ride.
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.
