1. Raptor frame. Short people 5'7" and lower should get the lower bike seat assembly. Moto seat if you are not going to pedal at all, or gonna go hardcore trail riding.

2. Rear shock 8.5" x 2.5" is good enough for just light street riding. For faster speeds go with 9.5" x 3.0". For max suspension travel go with 10.5" x 3.5". There is a list of suggested spring rates on the Qulbix website that will help you select the best spring for your weight, including shock mount location. Fox and Rockshox seems to be the good brands, but are pricey when going with the 10.5” shocks. You need 8x40mm shock spacers.

3. Dual crown fork of your choice with 180-200mm travel. I like my DNM fork for the type of riding that I do. Very smooth onroad and well behaved off road. Price is not as high as the bigger brand names. I’m not jumping 10ft off a cliff, so didn’t see the need for a more expensive fork.

4. Get a good handle bar with locking grips. A short stem is good. I have the Truvativ 40 0-degree 42 height 31.8 stem. I’m using ODI Rogue grips. Control Tech 4X handlebar.

5. I’m using a cheapy Shimano Tourney TX55 6/7 speed rear derailleur, with a Shimano Revoshift SL-RS31-5 5 speed twist shifter. Maillard 5 speed freewheel, which has a big center hole to fit the motor. I didn’t see the point of spending a lot of money for a derailleur that will get beaten up on the trails. It’s an electric bike after all and shifting speed and weight is not a priority.

6. Travativ Howitzer Team BB 83mm Shell 56mm chainline bottom bracket. Travativ Holzfeller 165mm Crankset. You can also get the schlumpf high speed drive from Qulbix. There are cheaper options that I’m still working on.

7. Control Tech 10mm offset seat post. 30.9mm x 350mm. Just cut the tube to your requirement.

8. Travativ Hussefelt II BB mount chain guide that fits 36-48T chain rings. However you can use a max of 40T chain ring.

9. Magura Louise brakes. Magura Julie HP-4F brake set, ebike version. I love Magura’s because they simply work. I’m not impressed with the more expensive brakes that are available. Those will work fine if you are a weight weenie and don’t mind having brake fade. Magura will have 4 piston calipers soon for mtb, that are based of their moto devision. Or just look for brakes that are used on downhill bikes.

10. 10k Ohms NTC thermistor for the temp option in the CA V3.

11. Wipperman 808 8 speed chain. It’s one strong quality chain.

12. Cane Creek 40 series ZS short 1-1/8” 44mm headset.

13. Alex DM24 36 hole wheel.

14. 18 fet sensored controller that at least uses 4110 fets. Get the program cable as well. Have the Regen brake option and 3 speed enabled. I’m using 21s Lipo on my bike.

15. I’m using the Cromotor for its massive torque and I don’t have to worry about overheating it under heavy loads. I can hit 45mph very quickly if needed. But I mostly ride 20mph, which consumes about 500W average with me pedaling along.
You can use a smaller motor, but just remember that it’s a heavy bike and care will have to be taken when pushing the limit of the motor. I believe the Magic Pie motor will be a solid option for a cheaper motor that will be able to handle up to 2000W without a problem. You can also look into the Crystalyte H40 series motors.
You can also use sensorless controller, but you will have to learn to control the throttle when pushing the limits of the controller. This is where the sensored controller shines.

16. Cycle Analyst V3 is needed for the best ride experience when running high power. My throttle and brake cutoff are wired into the CA. The CA then controls the throttle signal going to your ESC. Your bike won’t have a jumpy throttle, which can quite annoying when running high power setups. If your actual throttle fails for whatever reason, the CA will cut the throttle signal going to your ESC. Best safety feature available. And since your Brake cutoff and Throttle are wired into the CA, you will be able to use the cruise control function built into the CA.
I also have the amp limiter enabled through the CA. So I have a 3 speed limiter and amp limiter at my disposal.

17. Schwalbe Crazy Bob tires are good for this heavy bike. I’m using thick inner tubes. The rear wheel is 46mm wide and the Crazy bob’s sit well in them.
