CARING FOR YOUR BIKE

•
The most frequent maintenance necessary for a bicycle is to inflate the tires once a week and
to keep the chain clean and lubricated. We recommend any bicycle chain lube, but Tri-Flow can
be used for the chain and derailleur joints and pulleys. If the chain gets dirty or gunked up, good
chain cleaners are either isopropyl alcohol or Clean Streak. These can be sprayed directly onto
the chain and wiped clean with a rag or paper towel. Most bicycle shops offer complete drive-
train cleaning services.
•
The main components of a bicycle that wear out are the tires, brake pads, chain, cassette,
shifting cable/housing, and brake fluid or brake cable/housing. If the bike is being ridden almost
every day, these will likely all need to be replaced about once a year. Most bicycle shops carry
replacement parts that will fit our bikes. Nesta tires and inner tubes can either be purchased
online or directly from Espin by emailing us at hello@espinbikes.com.
•
All Espin bikes (except the Aero and some models before 2021) have hydraulic disc brakes. If
these brakes ever lose their stopping power, or if one lever feels squishier than the other, it
might be time for a brake bleed. Most bike shops offer this as a service. Our bikes have Zoom
hydraulic disc brakes and use mineral oil. DO NOT use DOT fluid. DO NOT get oil or grease on the
brake rotor or pads. This will ruin the brake pads.
•
Other components that can wear out over a much longer period of time are the chainring, de-
railleur pulleys, spokes, suspension fork, saddle, handlebar grips, and all of the bearings includ-
ing those for the headset, bottom bracket, and hubs. All of these items will likely be fine for at
least 5 years.
•
For e-bikes, the main component that can wear out is the battery. Espin batteries are rated to
maintain their charge capacity for at least 500 charge/discharge cycles. The hall sensor of the
hub motor can burn out, but this is a fairly rare occurrence and should always be brought up with
Espin at hello@espinbikes.com.
•
If the bike gets dirty or dusty, it can be washed off like a regular bicycle. First, turn off the pow-
er at the display, and turn off the battery for the Nero and Nesta. Leave the battery attached to
maintain the water-tight seal over the connection. Use a hose on the mist or shower setting to
rinse off the bike. DO NOT use the jet setting or high-pressure flow on any bearings or electrical
components. The bike can be wiped off with a soft cloth or paper towels. Leave the bike outside
to dry completely before turning the bike back on.

ERROR CODES

15 .1 Occasionally your display might show one of the above error codes with an H next to it. This
generally happens because a plug somewhere is loose due to jostling during shipping or after a
crash while riding the bike.
15 .2 All of the plugs on the bike are round, water resistant plugs with two arrows pointing to-
wards each other to indicate proper alignment. The seam for the plug is between the two arrows,
and can just be pulled apart.
15 .3 The inside of the throttle plug is orange, the display plug green, and the motor cutoff plugs
red. These 4 plugs are all located in front of the handlebar, and are in the middle of the cables
coming out of their respective components.
15 .4 The motor plug is underneath the non-drive side chain stay (refer to the bike diagram on
page 5). This plug has a metal ring on it that must be unscrewed before the plug can be pulled
apart. Espin models before 2021 did not have this ring, and can simply be pulled apart.
15 .5 The controller is located in the compartment between the pedals. To access this, remove
the panel on the non-drive side held in place with 4 bolts. All of the controller plugs and wires
are matched by color.
