It started out as a Juiced Bike HF1000 that I received in December of 2017. As of this post it has almost 3000 miles and has been going strong ever since getting rid of the stock controller.
Overall, I tried to make this the ultimate commuter bike, even though JB markets the HF1000 as a high performance off-road machine. My current commute profile takes me through about 20% suburban streets, 50% rural roads, and 30% urban stop and go. I only need to climb about 200ft of elevation, so the hub motor is a good choice.
I use this bike in conjunction with my 2016 Haibike Trekking S. With the increased power and speed of the HF1000, I'm able to cover about 16.7 miles in about 40-45 minutes travel time, compared to about 50-52 minutes with the Trekking.
As some of you might know I had some controller shutdown troubles starting around 300miles, I was sent a replacement controller from JB that I never installed. The other stock part that failed, was the suspension fork. I figured when traveling at higher speeds, I didn't trust the cheap fork that JB provides, and did an upgrade to a Bluto.
One thing that was discussed in the thread about the new HF1100 was the behavior of the controller. An ebike buddy of mine that works for a certain electric car company is convinced that the JB controller and MAC motor have a couple of issues.
1. The high power levels, over 30amps, that the controller provides to the motor is simply too much power to demand from a controller that has no airflow or way to dissipate heat.
2. The programming on the stock controller is not fully developed or was rushed out the door. A known issue that JB disclosed once the first few units shipped, was the motor would either get stuck in assist level 3 power levels, 1000w, when in Sport mode. The other issue was a weird cogging or bucking sensation that is characteristic of the controller not interpreting the Hall sensor of the motor.
The stock controller issue is what led me to go with the GrinTech unit. I must say that the saving grace of Juiced Bike is they used common connectors and the MAC motor was easy to interface with a different controller.
Overall I'm happy with all the mods and extra costs. I looked at this bike as a sort of "project bike" that I would rip apart anyways, so in the end it worked out.
Overall Pros:
- Amazing power and battery capacity, thanks JB for making a large format 21ah battery
- Smooth ride with the fat bike tires
- A beefy frame
Cons:
- Stock controller cutting out and surging
- Stock Mozo front fork seizing up
- Lack of a quick motor disconnect for flat tire changes in the field
- General commute problem - fat tires are like a magnet for roadside debris
A few other forum members have reached out to me and asked for a mod list and a few pictures. I suppose I should stop more often and take pictures as I pass through a nature preserve every morning, but here the bike is at the end of my commute.
Here's my list of mods:

- GrinTech PhaseRunner motor controller set and 37amps
- CycleAnalyst 3
- GrinTech 24 pole PAS sensor mounted on bottom bracket
- Supernova M99 Pro headlight

Handling:
- RockShox Bluto air fork
- DT Swiss BR2250 front wheel
- VeeTire Captiv8er font tire
- Origin8 SuperCell rear tire
- 203mm Shimano IceTech rotors
Touch Points:
- Ergon GP1 handlebar grips
- Ergon SFC3 saddle
- BodyFloat Suspension seat post
- Rock Brothers bell
Other Mods:
- Pletscher kick stand
- Third Eye Bar End mirror
