BPSA CLASSIFICATION - CLASS 1
A “Class 1 electric bicycle” or “Low-speed pedal-assisted electric bicycle,” is a bicycle
equipped with a motor that provides power assistance only when the rider is pedalling.
The maximum assisted speed of this e-bike is 15.5 mph.
CONGRATULATIONS ON THE PURCHASE OF YOUR NEW
E-BIKE!
The Delta mDrive is a new generation of e-bike designed and developed based on
many years of experience with our e-bike partner Promovec. Please read this user
manual as it contains important information concerning the safe use and maintenance
of this e-bike.
The Delta mDrive is a modern e-bike that has been manufactured following the latest
production standards and techniques ensuring you have the highest quality bike with
premium performance.
If you have further questions regarding your e-bike operation or assembly, please
reach out to us at 800-474-6615 or www.designbydelta.com for Delta Customer
Service.
INTENDED PURPOSE
The e-bike is intended for use on regular paved surfaces as well as upaved surfaces,
gravel roads and trails with moderate grades.
CAUTION
• Do NOT use the e-bike in combination with a bike trailer.
• Always use original Promovec spare parts when replacing electrical components.
• Do NOT clean the e-bike with a high-pressure cleaner.
• If the electrical system is modied the warranty is null and void.

WARNINGS:
• Using the e-bike outside the specied terrain may result in injuries and/or damage
to the e-bike.
• Wet weather impairs traction, braking and visibility, both for the bicyclist and for
other vehicles sharing the road. The risk of an accident is dramatically increased in
wet conditions, take proper precautions.
• Under wet conditions, the stopping power of your brakes (as well as the brakes of
other vehicles sharing the road) is dramatically reduced and your tires will not grip
as well. This makes it hard to control the speed of the bike and risk a loss of control.
To make sure that you can slow down and stop safely in wet conditions, ride slowly,
apply your brakes earlier and more gradually than you would under, dry conditions.

GETTING STARTED
Assembly of this e-bike is recommended by a certied bicycle mechanic.
If you choose to assemble your e-bike it is recommended that your bicycle be
inspected by a certied bicycle mechanic prior to riding.
It’s important to follow this assembly guide. E-bikes are great fun but improper
assembly can result in serious injury and/or death.
The tools you will need to assemble this bike are as follows:
• 4mm Hex Key (included)
• 5mm Hex Key (included)
• 6mm Hex Key (included)
• Multi-wrench (included)
• 15mm open-ended wrench and/or a dedicated 15mm pedal wrench
(Recommend)
• Snips or cable cutters (not included)
• Torque wrench (not included)
• Pump to inate the tires (not included)
• Grease for the pedal axle threads, stem and seatpost (not incuded)
We recommend using a torque wrench to check all the nuts and bolts that require
assembly to meet the required torque settings.
Once the e-bike has been unpacked, make sure you have removed all the packaging
and dispose of it appropriately – much of the packaging materials can be recycled.
Before disposing of the carton check that there are no remaining parts in the box.
When cutting zip-ties we recommend using snips or cable cutters to cut. Be very
careful not to cut any cables or wires.
We recommend using a bicycle assembly stand to help secure the bike during
assembly.

STEM ASSEMBLY
The handlebar comes mounted on the stem with brake levers and gear shifter mounted
to the handlebar. Insert the stem into the headtube and ensure the minimum insertion
mark is fully inserted into the headset.
1. Add grease to the stem, then insert it into the headset, the minimum insertion mark
must be fully inserted into the headtube.
2. Align the handlebars perpendicular with the front wheel.
3. Remove the rubber cover in the top of the stem expansion bolt.
4. Tighten the expansion bolt with 22-23 Nm in the stem ensuring the stem is xed in
position.
5. Place the rubber cover back into place.
6. Test that the stem cannot be removed or turned after installation.
HANDLEBAR ADJUSTMENT
It will be necessary to angle the handlebar to the correct riding position which is the grips
pointing down approximately 3-4 degrees from horizontal.
7. Loosen, but do not remove, both stem bolts.
8. Angle the bars in the correct position by pulling up on the grips.
9. Ensure the handlebar is still centered in the stem.
10. Tighten both stem bolts equally to 8-10 Nm.
11. Test that the bars cannot be moved up or down after installation.

WARNINGS!
• The stems minimum insertion mark must not be visible above the top of the
headset. If the stem is extended beyond the minimum insertion mark the stem
may break or damage the fork’s steerer tube which could cause you to lose
control and fall leading to serious injury and/or death.
• An insuciently tightened stem expansion bolt, handlebar clamp bolt or stem
angle adjustment bolts may compromise steering action, which could cause you
to lose control and fall leading to serious injury or death.
• Place the front wheel of the bicycle between your legs and attempt to twist
the handlebar/stem assembly. If you can twist the stem in relation to the front
wheel or turn the handlebars in relation to the stem, the bolts are insuciently
tightened.

STEM ANGLE ADJUSTMENT
The stem can be adjusted to raise the height of the handlebar to suit the desired riding
position.
1. Loosen but do not remove the wedge bolt located on the underside of the stem.
2. If necessary, loosen the bolts on the side of the stem.
3. Adjust the stem to the desired angle.
4. Tighten the bolts on the side of the stem to 8 Nm if they were loosened in step 2.
5. Tighten the wedge bolt on the underside of the stem to 14-15 Nm.
If you choose to change the angle of the stem it is likely you will need to adjust the angle
of the handlebars. Repeat the steps in the section “Handlebar adjustment” above to get
the correct angle for the handlebar if necessary.
WARNINGS
• Insuciently tightened bolts that controls the stem angle may compromise steering
action, which could cause you to lose control and fall leading to serious injury or
death. Ensure there is no movement by pulling up and pushing down on the stem,
properly torque bolts to the specied Nm.

FRONT WHEEL INSTALLATION
Bicycle wheels are designed to be removeable for easier transportation and for
repairing punctures. Align the disc rotor into the brake caliper and then insert the hub
axle on the wheel into the fork dropouts. The wheels are secured with the supplied
axle nuts and washers (where applicable) which are threaded onto the hub axle.
1. Ensure all the packing material is removed from the fork paying close attention to
the plastic fork protector at the bottom of the fork legs.
2. Remove the plastic spacer from the brake caliper.
3. Insert the front wheel into the fork by carefully aligning the disc rotor into the
disc caliper and then locate the axle into the fork dropout. Note: you may need to
loosen the axle nuts a few turns to get the axle into the fork dropouts.
4. Check the axle is fully inserted into the fork dropouts and tighten the axle nuts to
30Nm torque.
5. The wheel should spin freely and stop easily by pulling the left hand brake lever.
If the wheel does not turn or the disc rotor is rubbing on the caliper rst re-check
the above assembly sequence and check the axle is sitting correctly in the fork
dropouts.
6. If problems continue you may need to adjust the caliper – refer to Brake
Maintenance section or consult a trained bicycle technician.
7. At this point it is recommended you check the ination of both the front and rear
tires. Please refer to the Tires, Tubes and Wheels maintenance section.
