Choosing the right size for your Longtail cargo bike
One size fitting anyone between 1.55 m and 1.96 m
Information and recommendations on speed
The electrical assistance supplements your pedalling to help you reach your destination without overly sweating, while maintaining a pleasant pedalling pace throughout your ride.
The motor stops when you stop pedalling and when braking.WARNING: We have put in a powerful and torquey engine to accompany you when you are loaded.This motor generates power above 45 km/h which can damage your electrical system.Do not exceed this speed.
What are the characteristics of the motor on the Longtail R500E cargo bike?
Rear wheel motor: 48 volts, 250 Watt (nominal).
It has an engine torque of up to 58 Nm. It lets you easily carry loads of up to 170 kg.
The torque and power values tell you how easily the bike will deal with certain difficulties (such as a hill).
The motor is coupled to a torque sensor that provides electric assistance based on the force exerted on the pedals. It gives you a more natural pedalling motion.
Battery and battery life
Samsung lithium-ion battery
672 Wh (48V, 14Ah)
Charge time = 4 hours 40
Battery range: 90 km maximum in Eco mode (1), 70 km maximum in Normal mode (2), and 50 km maximum in Power mode (3) for someone weighing 80 kg on a relatively flat road with no load on the bike.
NB: The battery life may vary depending on the weight being transported (rider weight + weight of any items being carried), the gradient (uphill) and the weather conditions.
Control screen and trigger
There is an LCD screen just next to your left grip. You don't need to let go of your handlebar to choose between the 3 assistance modes: The modes are Eco, Normal and Power.
"Trip to go" tells you how much battery range you've got left, "Trip" tells you how far you've ridden, and "Odo" tells you the bike's total distance.
There's a start assistance trigger that helps you get going, up to 6 km/h (handy when heavily laden).
You can also control the headlights.
Assistance Modes
Mode 0 - Deactivated (battery not in use).
Mode 1 - Eco => up to 90% assistance on top of your pedalling effort.
Mode 2 - Normal => up to 180% assistance on top of your pedalling effort.
Mode 3 - Power => up to 300% assistance on top of your pedalling effort.
"Walk" mode => Hold the trigger to help you push the bike when you're walking alongside it (assistance up to 6 km/h) or to help you get started when riding.

Tyre maintenance and inflation tips
1) Monthly tyre pressure check (between 3.5 and 5 bar).If the tyre pressure is too low, you will lose efficiency, battery range and stability.
2) Regular drivetrain maintenance (especially the chain, which should be cleaned and lubricated).
3) For long-term storage (>1 month) without using the bike, we strongly recommend using the "extended sleep" battery mode to prevent any malfunctions.
Cleaning / Repairs
Before performing any work on your electric bike yourself (cleaning, electrical or mechanical maintenance), you must turn off the bike and remove the battery.

Use of the bike on the coast
The marine environment (air, ocean spray) is extremely corrosive for mechanical and metallic parts, so it is strongly recommended to regularly lubricate the entire drive train of your bike and clean the positioning elements with a damp cloth from time to time (handlebar, seat post, etc) to remove any salt deposits that may accumulate.
