Hi Richard! Good question, this is a new electric bike to me, never seen or ridden it. I do however, know of another electric bike that looks very similar called the
Volton Alation. I actually owned this bike and have ridden some of the newer models that have an improved battery pack cover design.
I like how the weight of the battery is built into the downtube keeping it low and centered on the bike. The 500 watt motor is very powerful and the bike offers both twist throttle and pedal assist! Though it uses a pedelec sensor vs. a torque sensor (meaning it doesn't respond as quickly or dynamically as you push faster/harder it's just like an on/off switch with different power settings).
For the price, the Volton Alation is one of my favorite hardtail mountain style electric bikes and I imagine the Predator would be very similar (they are probably made by the same manufacturer in China or Taiwan and just distributed under different brands to different regions in the world. It looks like REEF Bikes are from Australia.
A few things that set it apart from the Alation are the dual-high beam spotlight front headlight that is encased in metal (I saw something like this on the
Stealth bikes I reviewed recently (shown in the video reviews). The Predator also has a double crown suspension fork that offers long travel performance but probably weighs a lot more. This might not be a bad thing considering the weight of the hub motor in the wheel, the heavier fork might just balance it out.
Overall thoughts on this ebike are that it's medium quality with a more basic battery pack design. It's powerful, medium weight and the frame size is small/medium. The higher end 500 watt motor and 48 volt pack offer a TON of power and with the 26" wheels you get increased torque. Make sure to ride safe with this one and keep the rear wheel bolted on tight because if it comes loose the motor will spin in the rear drop outs and that will rip the wire out of the motor effectively destroying it. Let me know if you have any more questions! Maybe someone else here has actually ridden this bike?
