I think a lot of people have lost interest in these bikes due to the non existence of support. I know I have. My frame and motor are up for sale. I also have an empty battery case I got directly from Dengfu. I’m going with the HPC Trailblazer Fat Bike that was just released.

The website is gone

Sucks that they are gone but we saw it comin. Ironically I just started rebuilding my Hydra Fatty. Just need to get a battery made for it. I’m contemplating selling it and getting the new HPC Trailblazer Fatty. I have the MTB Trailblazer and it’s a phenomenal bike. The Fat Bike version has up to...

The E23 battery case can only support 15AH @ 52V. This was confirmed by Dengfu, Green Bike Kit, and a thread here on EBR. The specs for the bike show 17AH but that’s not what customers got.

So you are correct. According to this thread WW Hydra owners were lied to. The original battery is only 14 or 15ah. More salt rubbed into the wound of an already unpleasant purchase experience. Whats even worse is the website is still up like you can order a bike from them...

Can a battery case that is labeled for a 48V 17.5AH battery be used to build a 52V 17AH battery? The only battery cases I’ve been able to find for the Hydra (Dengfu E23) are 48V 17.5AH. My bike is an early Gen 1 Hydra so it was supposed to come with a 52V 17AH battery. That’s what I want to have...

My fat tire street bike. Running 27.5X4.0 Johnny Watts. Roll smooth and fast. I don’t have to worry about road irregularities, drainage grates, pot holes, curbs etc. Fat tires with the right kind of tread rule on the streets.

Updated pics of the bike. Just need a chain and the battery. I swapped out the NX 12 speed cassette for a Microshift 9 speed 11-46. It’s a beefy unit and designed for high power e-bikes. It’s made of hardened steel and is all one piece except for the two smallest cogs. I also have a much better...

Yes I can use the lower assist levels. In normal riding I only use 1-3 levels. My bike came with a 52V 17.5AH battery so that’s what I’m having built. I’m not sure what cells WW used when they originally built the batteries.

Love the Wren. Easy to adjust and doesn’t stiffen up in the cold. Only downside is the max tire size is 26X4.8

Hi Power Cycles is building the battery. I have their 1800 watt Trailblazer which is an awesome bike. I know they will make a battery thats more than capable of handling the power. What I’m stoked about is now that the frame the bike uses is known owners can get motor/battery kits from multiple...

Bike is done! Keeping the 2300w power level and having HPC build me a battery to support the 60a peak needed for that level. Have to wait for the battery until after the holidays but man it will be good to have this beast back on the trails.

So I‘m keeping the power level at 2300 watts. I’m using a chain so hopefully it will hold up. I did find out the frame is a Dengfu E22 with a different rear triangle for the fat bike. Any motor and battery kit for the E22 will fit the frame. Also suspension linkage parts you can get directly...

Project Fat Hydra Revive has begun! I’m not getting into the background story because it’s just too long and I’m past it now. I‘ve had the frame and motor from this bike sitting around and collecting dust and I’ve been wanting to do something with it so I’m not out the money I spent on it. In my...

Website is still up and nothing on the FB page about being out of business.

Thanks!

Anyone know what size shock the gen 1 Hydra’s use?

Check out the HPC Trailblazer. I have a frame kit on order from them. Available in 750w to 1800w. Not sure if they ship overseas.

This. I wouldn’t buy s*it from WW.

Well the SRX is not a hub to have in a high power ebike. It only has 3 sets of pawls so I‘m pretty sure it will fail at some point.
