INTRODUCTION
Thank you for purchasing a Converted System Summit conversion kit. We are condent you will enjoy
the freedom riding electric brings.
Bike/frame selection - The mid drive unit ts many dierent bike frames however some t better than
others and there are some which unfortunately won’t convert. Generally speaking a basic hard tail(no
rear suspension) bike with a traditional tringle frame will be the easiest conversion.
If you have a bike already and are unsure or if would like to buy a bike for conversion please contact
us and we can give guidance... we have converted hundreds.
We have created printable templates as guides for battery and motor tment. these are available for
download from our website.

Consumables/extras- items you may consider
• Extra cable/zip ties - some bikes need more than others
• Shift cable(core) - it can sometimes be dicult to a install shift sensor with an old cable
(especially with frayed end) as you need to slide it onto the cable.
• New chain - We advise ting a new chain. remember you have just added more power to your
ride. A tired old chain may not like it,
• Cable extensions - We’ve tuned the cable lengths to cover most bikes, but if you’ve got a special
build or cargo bike you might need some extensions.

3. BIKE PREPARATION
Installing your Converted System Summit kit is not hard, but you do need a certain
level of mechanical knowledge. There are plenty of online video tutorials on youtube
should you get stuck. Otherwise contact us and we can help you out.
3.1 Bike /Frame preparation
The Converted System Summit kit uses a Bafang mid-drive motor which replaces your existing
cranks/Chainring(s)/bottom bracket. The folowing instructions relate to frames with a standard
threaded bottom bracket, which is currently the most commonly found type. The internal diameter
is 34mm and the width between 68-73mm. For other styles of bottom bracket you may require an
additional tting adapters. Please contact Converted System for further info. as required.
3.2 Cranks/bottom bracket/front derailleur
Remove the pedals from the original cranks if you are planning to re-use (generally 15mm spanner
or allen key, Left pedal is reverse thread - turn clockwise to loosen)
Remove cranks,
• Remove the centre crank bolts (normally 8mm Allen Key)
• Using a crank extractor tool remove the cranks, (see manufacturer instructions).
If the bike is tted with a front derailleur, break the chain to allow removal.
Disconnect the front deraileur cable and remove the derailleur bracket (this normally clamps around
the seat tube).
Remove the bottom bracket with a Bottom bracket removal tool. Start on the left(non-drive) side of
the bike. removing the cup completely.
Repeat on the opposite(chainring) side, this will be reverse thread so turn clockwise to loosen.
The bottom bracket should pull out completely.
Remove the front derailleur cables.

3. BIKE PREPARATION
3.3 Handlebars
Some times it is easiest to remove everything o the handlebars before reinstalling in prefered
order. The end setup of the handlebars comes down to personal preference, however you will no
longer be running a front derailleur so the shifter can be completely removed.
If your bike is set up with cable brakes*, it is advised to replace with the included levers which
incorporate cut-out switches which cut motor power when the brake is operated.
*Hydraulic brakes - For bikes with hydraulic brakes you may wish to run your existing brakes without
cut-o. Converted recommends running some form of motor cut-o for safety. We can provide
Tektro E-350 hydraulic E-bike brakes with built-in sensors or a manual cut-o switch. Sensors are
also avabilable however suitability will depend on your individual setup and brake lever design.

4.1 Bottom Bracket Preparation / Motor Fit
The folowing instructions relate to the standard threaded bottom bracket, which is currectly the most
commonly found type. The internal diameter is 33.6mm-33.9mm and the width between 68-73mm.
For other styles/sizes of bottom bracket you may require additional tting adapters and spacers.
Please contact Converted System for further info.
Ensure that the bottom bracket (BB) is clean, free of weld debris (you may need to le to get motor to
slide in). The motor should be able to swing up till it comes in contact with the downtube.
Ensure the motor can be inserted fully and sits with the drive side at against the botom bracket shell
without touching chain stays etc.
For rear suspension bikes, ensure the pivots are clear of the casing for the full range of movement,
else spacers may be required to give adequate clearance.
Fit the BB axle torque plate facing with the teeth facing the frame. Loosely tighten the M6 bolts (nal
tightening will occur in the next step). Use low strength Loctite
4. KIT INSTALLATION
WWW.CONVERTED.CO.NZ
Holding the motor against the downtube, using a lock ring tool or C-spanner (see pic) tighten
both the M33 lockring (33-40Nm torque) and the BB cup over the M33 (20-30Nm torque).
Lock ring socket tools are available to purchase through Converted System.
Tighten the M6 bolts to nal torque (34-40Nm).
