review of my wattwagon full suspension bike

I think the picture makes it look a little more tilted up than it is

but it seemed ok the past few days

Need to get more rides on it and longer rides
may end up adjusting it some the next few weeks

Vincent, how do you like your Jones Bar? I'm thinking of getting a Jones bar for my next ride.

Is yours the 770 or710 mm?

City explorer I use throttle very little , pedal all the time

Use it to get across a busy road faster and sometimes to get the bike slightly rolling on a hill

Deacon Love the jones bars, have had them on 4-5 bikes now

If I remember right got the longer ones because I figured we could shorten them if needed, but they seem ok so haven’t yet

It looks very nice, but I wouldn't trust that rear suspension design 50' from the looks of that first picture. Far too lightweight. I can't believe what I'm seeing, they mounted a rear suspension pivot point there at the tail end of the top tube? From an engineering stand point, that makes no sense, and the components look like they're not made of sturdy enough material to withstand a lot of stress and shocks. If this is what it is, a heavy electric bike that will be used off road primarily, the mantra is to over design it, not under design it. A stress fracture of a top tube would be catastrophic.

Not sure if he is factoring in it's a titanium frame (so perhaps you can get away with more than you might otherwise). As far as rack design, the unsprung mass will affect the suspension dynamics (since the rack is attached to the swingarm which isn't suspended). I wish there were more FS options out there besides R&M suspended rack but looks like Dost is toying with it for a future bike. Note how the rack is attached to the suspended frame instead of the swingarm in the mock up below.

ok so the worry is the rack may not hold up long term to weight? or that the rear suspension parts will have problems eventually?

i am heavy but riding the bike pretty light to medium, do not jump anything and try to avoid harsh bumps etc
to be clear i ride dirt roads that are washed out etc but am not mtn biking this or ever going fast on bad terrain

maybe i should go with a front rack also in order to spread the weight around, was considering this anyway - i tend to carry a decent amount of stuff with me

got in another 30 mile ride on dirt roads today and it handles/rides really well, very pleased with the bike
if it does not rain may do a 65 mile ride tomorrow

I think it's fine. The suspension just won't perform as well as if the rack weight was unsprung. In theory you want minimal unsprung weight on the wheel so that the rear suspension can do it's thing (court has a video on unsprung weight if you google it). I have similar concerns with my yet to be received Frey CC. The feedback I got from those that had ridden it was that it works well enough and provides more options than not having a rack.

You seem to find the suspension doing its thing to your satisfaction. That's all that ultimately matters. ;)

excited to hear about your frey cc, i considered that one but the weight scared me off- think my ww came out about the same though
when is the frey supposed to get here?

hoping to ride to the bike shop tomorrow and talk over/look at front rack and front bag stuff

at this point i am planning to get a little more weight on the front end anyway so maybe that will help some

will watch courts video

got an ortlieb roll type bag for the front, it fits with my small jones bar bag in the center of the handlebars

think it is overall good to distribute the weight better, even for the life of the bags

did a 60 mile ride yesterday and the bike did great, took both batteries and swapped in the middle of the ride , 1st battery was at half
used about 13wh per mile, mostly 15-16mph
some dirt but 75% paved, last 20 miles into the wind

this is a little faster than i usually run on the forest roads so hope to do a little better wh wise on those



only did the math on 2 other rides, 40 miles and 13 wh on those 40 miles

1 ride with 29 miles i think and used 16/17 on that one, more windy and 15mph that ride

have not been watching my battery usage at all , this is just about where all my bikes end up on wh i think

overall have ridden about 150 miles on it the past week and very pleased with how smooth the bike is and how the rohloff does


on another thread we are discussing how to carry extra batteries in bags- got an ortlieb computer insert for the panniers and think this is going to help a good bit
need to get more pictures tomorrow and then will post about that

steve will update this if any problems with the frame in the future
but my understanding is pushkar commuted on a frame just like this - most likely at much higher speeds than i ride - for hundreds if not thousands of miles

will keep an eye on it for cracks etc

i know nothing about this stuff, but the bike rides super smooth

hopefully the titanium is tougher and my mild off road riding will be ok for it

sure pushkar has more insight on this , and him and the frame builder felt it will be fine

Vincent, in one of your posts you mentioned a clunk from the drive train. A couple of days ago I took out a Biktrix full suspension Ultra and heard the same thing. I wonder if this is a common trait with the ultra motor.
You're sure racking on the miles. 👍

Deacon that is definitely an issue with this motor although I think mine is a little better with this different programming on it

There are quite a few threads here and on a couple of other forums talking about this, for me it seems to depend a lot on what terrain I am on and how fast I’m going, mostly notice it when it’s very slow and on pavement

OffRoad I barely noticed it at all

I have high hopes that with some more programming and possibly some different controllers that we can get this quite a bit smoother

But this may just be a trade off for having 160NM....

using the front ortlieb roll bag have redistributed the weight some and feel this is overall better

got another 30 miles off road yesterday and cannot get over how smooth this bike is, my arms and shoulders are never tired after riding no matter how long, big improvement from all the other bikes

looking forward to some 75-85 mile rides this summer

Thanks for the kind words. This means a lot! Thanks for being patient and persistent. Your suggestions definitely helped me get better!

Will the new large capacity battery fit on this bike with a larger frame size?

Zero clunking in my 2017 Biktrix Ultra. Whether or not, It might be the steel gears, I don't know , because I still have the nylon.
