Stealth bikes are partially disassembled for packing. Several components must be reassembled before riding. Batteries are
sent separate to the bike for non-Australian customers.

•A set of metric Hex Keys (2, 2.5, 3, 4, 5, 6, 8, 10mm)
•A T25 Torx key
•15mm pedal spanner
•Calibrated torque wrench with hex key attachments
Stealth Electric Bicycles should only be assembled by a skilled mechanic. If you are not confident with

2. INSTALL THE FRONT WHEEL
For ease of transport, your bike may come with the front wheel uninstalled. The 20mm thru axle needs to be correctly
inserted into the dropout when installing the wheel.
DNM forks
MRP or SR Suntour forks
If your bike is equipped with MRP or SR Suntour forks see their respective manuals for wheel and axle installation.
3. INSTALL THE PEDALS
The B-52 model may come with the cranks removed from the SR Suntour V-boxx. To install these cranks insert them onto
the axle on either side of the bike. Make sure the cranks are parallel and oriented opposite ways. They are tightened with a
torque wrench hex key to the specified torque value.
The other stealth models have the cranks already installed. The pedals need to be installed on the correct side. The right-
hand crank and pedal has a standard thread and the left side has a reverse thread. The pedals should be tightened by hand
Remove stem cap

first to ensure they are not cross threaded or have the wrong thread. Using a hex key or pedal spanner the pedals can be
tightened to the prescribed torque.
Stealth B-52:
Pedals come pre-fitted to the cranks at delivery. The pedal/crank assemblies can be installed using an 8mm Allen key.
I. Ensure pedal is securely fastened to the crank.
II. Connect pedal/crank assembly to gearbox being careful to match left
and right cranks to their respective sides (cranks are marked with L and Ras
shown).
Stealth F-37 and Stealth P-7:
Cranks come pre-fitted to bike. The pedals can be fitted using a 15mm pedal spanner.
I. Unwrap pedals and separate left from right if labelled. If not labelled, the
right pedal always has a standard thread and will only tighten CLOCKWISE into
the right crank. The left pedal is the opposite.
II. Tighten pedals on to their respective cranks using an 8mm Allen key if there
is no surface for a 15mm pedal wrench.
4. INSTALL THE SEAT POST (STEALTH B-52, F-37 AND P-7 MODELS)
The supplied seat posts are extra-long and suitable for taller riders. Shorter riders may find that they need to cut the length
of the seat post to avoid contact with the rear shock. Avoid contact between the shock spring and the seat post and make
sure that the shock will not contact the seat post when the suspension is fully compressed.
I. Bolt the seat to the post loosely.
II. Slide the seat post into the seat tube and adjust the height accordingly.
III. Adjust the tilt of the seat back and forth using the adjusters located on the seat post.
IV. Tighten all bolts. Ensure that there is always a minimum of 50mm of overlap between the seat post and the seat
tube (frame).

6. INSTALL THE BATTERY (FOR STEALTH B-52, F-37 AND H-52 MODELS)
If your battery has been shipped to you separately you will need to install the battery into the bike.
Check that the seat post will not
collide with shock under full
compression before riding
Loosen rear bolt
Fit clamp to seat rails.
Tighten bolts to get desired
seat angle.
Ensure key is removed when performing any work on bike. Accidental acceleration of bike may cause
serious personal injury.
