Eunorau S1 Overview
The Eunorau S1 is an electric dirt bike sized for kids and teens. There are no pedals: the rider stands on footpegs and twists the throttle, and a 60V mid motor that peaks at 4,800W and makes 150 N.m drives the rear wheel by chain. Eunorau rates it at 43.4 MPH.
It rides on a 14 inch front wheel and a 12 inch rear, with an inverted fork, an adjustable rear shock and hydraulic disc brakes on 190mm rotors. Eunorau fits it to riders 4'9" to 5'9" and up to 220 lb. The 60V 30Ah battery is UL certified per Eunorau and good for up to 24.8 miles; a full charge takes about 7 hours.
It is for private land and off road trails only, and Eunorau recommends adult supervision and protective gear on every ride. Bigger rider? The Eunorau R1 comes in a Compact and a Full Size.

PULL FOR THE CLIMBS
The 60V mid motor peaks at 4,800W and makes 150 N.m of torque, and it turns the rear wheel through a heavy duty 420 chain on an 11 tooth front and 60 tooth rear sprocket. Eunorau rates the top speed at 43.4 MPH.

SOAKS UP THE TRAIL

Questions before buying
Who is the S1 for?+
Eunorau builds it for kids and teens about 4'9" to 5'9" tall, up to 220 lb including gear. The seat sits 28 inches off the ground. Eunorau recommends adult supervision and protective gear on every ride.
How fast does it go?+
Eunorau rates it at 43.4 MPH. That is real speed for a young rider, so start in an open space at low speed with an adult watching. Eunorau's page does not list a parental speed limiter.
Is it street legal?+
No. Eunorau sells the S1 as an off road dirt bike for trails and private land. It has no pedals and reaches 43.4 MPH, so it is not an electric bicycle under any state's rules. Check your local rules for where it can be ridden.
How far does it go, and how long does it take to charge?+
Eunorau rates it at up to 24.8 miles on the 60V 30Ah battery, and about 7 hours to charge from empty. Rider weight, hills, sand and a heavy throttle hand bring the range down.
What terrain can it handle?+
Dirt trails, grassy paths and uneven ground, per Eunorau. The inverted fork and the adjustable rear shock take bumps and small jumps, and the knobby 14 and 12 inch tires grip dirt and sand.
S1 or R1?+
The S1 is the smaller bike, on 14 and 12 inch wheels with a 28 inch seat, for riders 4'9" to 5'9". The Eunorau R1 is a 72V bike that reaches 55 MPH, in a Compact or a Full Size, for bigger riders.
Does it arrive assembled?+
Not fully. Eunorau posts assembly videos for the last steps. The bike weighs 152 lb, so have a second person there to lift it out, and photograph any box damage before you unpack.
What does UL certified mean?+
It means the battery was tested by an independent lab against a published safety standard for electrical and fire risk, which matters for a 60V battery you charge at home. Eunorau lists the S1 battery as UL certified.
What is the warranty?+
Eunorau covers the motor, battery and electrical parts for 24 months, for the original owner. Wear parts such as brake pads, rotors, tires, chains and grips are not covered, and neither are crashes, stunt riding or racing. Eunorau asks you to register the bike right after purchase and to have it checked by a Eunorau dealer after the first year. We are an authorized dealer, so the warranty applies.
Orange or Camouflage?+
Same bike, same price. Orange has orange and white graphics on black panels; Camouflage has grey camo graphics. Both run black wheels and a black frame.
