*XT60: 2 pin, 60A rated, Soldered. Very good connector but no anti-spark functionality and hence best only for occasional disconnections.  
Mounting a rack to your bike is a very simple process that requires very few hand tools outside of an Allen key set and maybe a wrench. Racks mount to 2 threaded holes in the frame just behind and below the seat, as well as two threaded holes just above the rear axle.  


*MT60: 3 pin, 60A rated, Soldered. Good connector for phase wires.  
If you lack the hole on the upper part of your frame near the seat often your seat post clamp can be replaced with one that has the required mounting holes. Do note that you will have to measure your frame as seat post clamps come in different sizes.  


*Anderson Powerpole: 40A rated, Crimped. Very good connector that has a sacrificial tip designed to take the wear of sparking without eroding the main contact area.

*JST-SM: Low current rated, Crimped. Good for signal lines like throttle and very low power like LED turn signals and such. Good connector for hall sensor wires.
If you lack the lower mounting points, P clamps or a rear rack with clamp on support tubes can be used. Please note that if you have rear suspension that you are pretty much limited to the kind of rack that clamps on to the seat post and has no side  supports. Seatpost only racks generally bad to mount side panniers on as nothing stops the pannier from hitting the rear tire.  


*Higo: An over-molded type of connector that can't be easily used in DIY as you have to splice to a pigtail to use one. Water proof and very good, comes in many formats and current ratings including combined hall/phase wires for motors. Highly recommended to get if you can find a controller and accessories already using them.
==What rack is right for you?==


Your rack has to physically fit your bike. This means your bike must have matching mounts and at the right width apart. The rack must also clear the rear tire. Most racks are designed to be adjustable from 26" to 29" tires, but some may not. Do check the description before buying. It is also important to get the width of the rack correct. Fat bikes will require fat racks, and some bikes put the rear disk brake in a place that obstructs some racks.


Connectors we don't recommend:
Here are some examples of rear racks:


*Bullet connectors: These are generally only good for around 15A, often have poor tolerances and can come loose with vibration and melt even when used at rated current levels.

*Spade connectors and terminal blocks: Often found on the phase wires of cheaper motor kits, these connectors often are of poor quality and melt under the currents.

==What pannier bag to pick?==
 
Consider your shopping requirements when buying panniers. Make sure it is big enough for everything you plan to buy, some items like frozen pizzas won't fit in smaller panniers. Also consider you can wear a backpack as well for even bigger grocery trips for storing very fragile items like bread, or bulky items like 4L jugs of milk in the backpack while the rest goes in the panniers.

Panniers are storage bags for your e-bike. Rear racks and pannier bags are by far the best way to transport things on your e-bike. While backpacks can work the extra weight they put on the rider can be uncomfortable and makes it slightly more difficult to ride.

Rear racks come in 2 basic styles. One that mounts off the seat post alone and is generally good for up to 20lbs max and the style that bolts to the frame below the seat and just above the rear dropouts that can handle much more weight.

Mounting your rack

Mounting a rack to your bike is a very simple process that requires very few hand tools outside of an Allen key set and maybe a wrench. Racks mount to 2 threaded holes in the frame just behind and below the seat, as well as two threaded holes just above the rear axle.

If you lack the hole on the upper part of your frame near the seat often your seat post clamp can be replaced with one that has the required mounting holes. Do note that you will have to measure your frame as seat post clamps come in different sizes.

If you lack the lower mounting points, P clamps or a rear rack with clamp on support tubes can be used. Please note that if you have rear suspension that you are pretty much limited to the kind of rack that clamps on to the seat post and has no side supports. Seatpost only racks generally bad to mount side panniers on as nothing stops the pannier from hitting the rear tire.

What rack is right for you?

Your rack has to physically fit your bike. This means your bike must have matching mounts and at the right width apart. The rack must also clear the rear tire. Most racks are designed to be adjustable from 26" to 29" tires, but some may not. Do check the description before buying. It is also important to get the width of the rack correct. Fat bikes will require fat racks, and some bikes put the rear disk brake in a place that obstructs some racks.

Here are some examples of rear racks:

Rear rack for most mountain bikes, rated 55lbs on Amazon.ca Amazon.com Note: might not fit all bikes with disk brakes. Won't fit fat bikes.

Rear rack with extra clearance for disk brakes that would be in the way of other racks. On Amazon.ca Amazon.com

What pannier bag to pick?

Consider your shopping requirements when buying panniers. Make sure it is big enough for everything you plan to buy, some items like frozen pizzas won't fit in smaller panniers. Also consider you can wear a backpack as well for even bigger grocery trips for storing very fragile items like bread, or bulky items like 4L jugs of milk in the backpack while the rest goes in the panniers.

Notes

Note there are many other seat post clamps, racks and pannier bags available online. If you don't live in Canada/USA, consider ebay and other online cycling specific stores and your local bike shop. The local bike shop can be great as you can often test fit the rear rack by holding it up to your bike and make sure it will mount properly before buying it.
