Q45 - First Two Rides ...

I picked up my new Q45 from Hamilton Trike & Bent (#HamiltonTrike) in mid-November, just as winter was approaching so I really didn't have a chance to ride at that time. However, as the snow is finally melting in Ottawa, I was able to get out for my first two real rides on my new Q45 this weekend!! Thought I'd share my experience for others that may be wondering if they should pick up a Q45 for themselves ...

For reference sake, I've previously owned an HP Velotechnik Spirt and an HP Velotechnik StreetMachine GTE. The used Spirit which I picked up was my first recumbent. I enjoyed it, and it was a great start into the world of recumbents for me, but eventually I found myself looking for something a little faster. A colleague had a StreetMachine which he was interested in selling so I purchased that and rode it for 3 years. I successfully completed the Rideau Lakes Cycle Tour (174 km from Ottawa to Kingston on a Saturday, and 174 km back to Ottawa the next day) with my StreetMachine - I was the only recumbent of 2300 participants, and the only person walking normally Saturday night in Kingston :)

While the StreetMachine was a wonderful bike (HP Velo truly make amazing stuff), for a variety of reasons, I found myself looking for something that had a more upright seating position and something that I could stabilize with my feet on the ground faster for times when I needed to come to a sudden stop. After researching a number of alternatives, I ended up purchasing a new Q45 last November.

Back in November I spent about half an hour practicing the new rider techniques suggested by Cruzbike. As I was used to recumbents, things felt quite good and I was doing figure 8s within a few minutes. Yesterday, before starting out on a "real ride", I spent about 15 minutes in an empty parking lot practicing starts / stops, figure 8s, etc. Once things felt okay, I headed out on some of the numerous bike paths in Ottawa. I ended up completing 20 km yesterday. This morning I went out again and completed a 25 km ride on some different paths. All of my rides were on asphalt roads and paths.

Overall, I'm thrilled with my Q45.

I've spent some time this afternoon comparing the Strava segment times using my Q45 vs what I achieved with my StreetMachine. In most cases, the Q45 is coming very close to the StreetMachine which is impressive given how little time I've spent on the Q45, and that my current conditioning level is not particularly good after a long winter hibernating! The ride position is much more upright than my StreetMachine which makes for a safer ride in my opinion - it's much easier to turn my head to look for traffic at awkward angled intersections for example. It is also much easier to put my feet down and stay stabilized when I need to come to a full stop. While clearly subjective, I think I've had a slightly easier time climbing hills on my Q45 than my StreetMachine. I have a couple of short but very steep hills on one route which I have yet to try on my Q45 - that will be a very interesting challenge which I'm anxious to try on my Q45. I certainly made it up every hill I've experienced to-date with no issues whatsoever.

I clearly still need more time learning how to ride my Q45 - sadly 45 km does not make you an expert!! ;) I've noticed I've got a very tight grip on the handlebars which I need to learn to relax. I also need to learn how to "steer with my feet" as I've read about others doing on their Cruzbikes. Finally I need to get more comfortable doing tighter radius turns at slower speeds - the balance isn't quite there yet and I find myself dropping my feet.

The Ventisit seat has been okay but not as comfortable as what I was used to on my StreetMachine. I've not experienced the numbness some others have written about, but my rides haven't been super long yet either. Hopefully my body will get used to the seat, otherwise I may have to explore the Thor seats I've seen folks referencing in these forums. I've not felt the need for a headrest yet (never had one on my StreetMachine either).

I do wish I had some higher gears. On a couple of the downhill segments I rode this weekend, I was in the highest gear possible but I was unable to apply any force to the pedals - they just spun freely as I guess I was going to fast for that gear?? I'd love to hear of suggestions on how to modify the stock gearing to give me some additional gears at the high end.

I'm not sure if I need anything else on the low end of the gears yet. This weekend I had no issues getting up all the hills I encountered, and I was typically in 2nd or 3rd - don't think I was ever in first gear. But I know there are some tougher hills in my area so I'll find out in future rides if the low end is low enough for me or if I need to try to expand that as well.

I do miss the internal hub gearing I had on my StreetMachine - so much nicer to be able to switch to a low gear when you're stopped at an intersection …

Finally, two other questions for the knowledgeable folks out there…

a) does anybody know if it is possible to get a bracket of some sort to be able to mount a light at the very front of the Q45 (end of the boom by the chainring)? There seems to be a piece of metal sticking upright with a hole in it - not sure if some sort of adaptor is available that would allow me to clip a light in that area - seems to me like it would be a great spot for a headlight.

b) does anybody know if there is any way to further adjust (or replace) the stock suspension that comes with the Q45? On my rides this weekend I definitely felt some bumps much more than on my StreetMachine and thus I'm wondering if there are any improvements possible ...

That's it for now! Sorry about the lengthy post but I figured it might be useful to prospective Q45 purchasers … (and my recommendation is a hearty - buy one!!)


Cheers,
Gary

Hi Gary -- new-ish Q45 rider here. Good to hear about your experiences getting acquainted with the machine.

Regarding boom-mounting the headlight, the Origin 8 light mount stub is indicated for the Q. It is available in the Cruzbike store.

And as regards shock upgrades, the Kindshock A5-RR1 seems a widely accepted one for the Q. I've had mine a couple of months now, and have been quite pleased with its performance.

Welcome to the Q!

Joe

Welcome Gary!

I bought my Q45 the first day they were offered in 2018, and have been smiling ever since. You are correct that the tight grip you have on the handlebars will ease up over time. A couple of your questions were already answered, but here's my take on some other issues you brought up.

I think the only option for a wider range of gears would be to go with a 2x system because I think the 11-42 cassette is the biggest that will fit. I have had the same issue with spinning out at the high end above about 26 mph. I don't want the complication of adding a 2x, and I need the lower gears because of the hills I have in my neighborhood, so I just accept not going faster. The only thing I did when going to Bike Sebring in February was get a 50 tooth front chainring so I could go faster. There aren't any real hills in Florida, so it worked fine. I have the 38 tooth back on now that I'm home.

After doing an 800 mile ride in a week with Biking Across Kansas in 2018, I did have some recumbutt with the stock seat. I decided to get the Thor with the headrest, and I don't regret it one bit. Mine is set at about 35 degrees and since the Thor is contoured nicely, I haven't had any problems, even with a coast to coast 2,800 mile ride in 2019.

Enjoy your rides!

And about steering with your feet - in my opinion it's to soon, give it some 150-200km more before trying that. The issue in my case was that the muscles required to do it just weren't there yet, since for it a whole new group of muscles is being used, which I didn't even knew I had! :) Now, after 2400km, I don't even think about it, in my opinion it's easier then riding the DF without hands.
About recumbutt, the only time I had the chance to go on a longer ride is when I rode 211km in one day at the beginning of march. The issue comes after 3 hours of not stoping, but if I made brakes more frequently, there were no issues.

It looks like the Kindshock A5-RR1 comes in a few different sizes. A quick search on amazon.ca came up with 125x20mm, ST1441, 165x40mm #ST1662 and 150x30mm #ST1442.

Might anybody know which of these I would need for my Q45?

Thanks again,
Gary

See post #3 of this thread. The Q45 page of the Cruzbike main website says 165mm.

Thanks Ben. I thought the 165 mm in your post 3 was referring to the Origin stub not the shock!

So the 165 x 40 ST1662 should fit then. ….. many thanks!

Maybe I don't know whats comfy but the stock shock is really comfy for my weight (95kg), I even added a bit of preload since the rear rack is rarely empty (5kg to 15kg) so I wanted to avoid bottoming out.

I tried all sorts of positions for the light, and the factory postiion is the best in terms of lighting. However, it's not very practical while storing the bike, it's the first thing that is going to hit something.

Probably no reason for it, but it sure looks like you could even go with a longer shock if you wanted. Just give it a bit more sag when setting it up.

I am planning to buy the Kindshock A5-RR1. I've not had any luck in finding online manuals for it. Does anybody know what pressures should be used in each chamber?
Thanks in advance!

Thanks in advance!

The most important thing is that the main-chamber pressure must be higher than the negative chamber.

I use about 25psi more than my body weight in the main, and about 25psi less in the negative.

Just play around with it. Pick a stretch of bumpy road, ride back and forth, adjust, repeat. It's easy enough to do so you can adjust according to the expected ride conditions. I'd say stiffer if you're doing a lot of climbing.

(Since you can only reach one of the two valves without undoing the shock mounts, make the main the one you adjust on the fly. Set the negative to something below your body weight, tweak the main. It's not a big deal to undo the shock mounts, though.)

Use the o-ring around the piston to see at a glance how close you are bottoming out. Very convenient. I like to see no more than half the exposed length of travel. If I see more, I'd pump up the main.

BTW, the length for a Q45 is 165mm. I guess you could get longer, but that would change the geometry. Shorter wouldn't work because the seat post might hit the rear wheel, more so if you have a fender. Definitely want to avoid that.

Many thanks for your timely reply! My shock (165 mm) arrived yesterday and I was hoping to install it / get out for a ride this afternoon before the rains come for the rest of the weekend.
I'll happily take and use your advice.

Cheers,
Gary

Exposing the main valve means having the shock body on top. I can't think of any reason why the orientation would matter. Maybe it does??? Any opinions?

A quick update on the shock … I installed it this afternoon and went out for a 10km ride. I was able to install it with the main chamber valve on top (closest to the seat) and was still able to access both the main and negative valves to adjust the pressures while the shock is installed. I did have to increase the pressure a fair bit to prevent the bottom of the rack on the back from hitting my fender.

I'm not sure if it is my imagination or not, but after 10 km I found:
- the steering felt different --- hard to explain, but it seemed as though it was more sensitive than before the shock change
- my left knee is sore after the ride --- I've never had knee pain on any of my other rides with my Q45

So is it possible that the air shock, with the pressures high enough that the rack doesn't bottom out, has changed the overall geometry a bit to result in the two effects I noticed today?

I'll try a few more rides later this week once the rain stops, but thought I'd reach out for your opinions in the meantime.

Many thanks again!!

The air shock stiffens the frame. To me, that's one of its big advantages. Yes, that makes the steering more sensitive, and also more precise. I feel more "one with the bike" using the air shock. The frame is not flexing when I push hard on the pedals.

I don't have a rack, but I do have a fender that extends a fair bit above the rear wheel. I have to keep my main chamber pumped up or else the seat post hits (and breaks!) the fender. But I thought the rack was made to fit on both sides of the wheel so it wouldn't hit it even if the shock bottomed out.
