Salsa Confluence: The Good, The Bad and The Fun
1 year ago
As an avid gravel cyclist, I’ve been eager to enter the e-bike scene. My main goal was to find a bike that would reduce the effort and sweat of my 16-mile commute to work while also being suitable for local errands. I needed multiple mounting points for racks and bags but still wanted the sleek look of a gravel bike. Admittedly, the look of most e-bikes didn’t appeal to me until I discovered the new Salsa line, which met all my needs. Here’s what I like: • Lightweight for an e-bike • Good battery range. My 32-mile round trip to work with roughly 1.5k feet of climbing leaves me with 30-40% battery remaining when I get home • Smooth pedal assist from the torque sensor • Lots of mounting options • The MAHLE app is user-friendly, providing real-time battery percentage, mileage left, and map navigation • Reasonable price point • Option for an external battery range extender What I don’t like: • I was very interested in the Salsa Apex 1 but was disappointed that a $2,500 bike (MSRP 6/24) didn’t come with hydraulic disc brakes. This led me to the Confluence model, which does have them. With the weight of an e-bike, you need maximum stopping power, and cable brakes don’t suffice. • The assembly quality was below my expectations for a $3.5k bike. Whether it was REI or Salsa at fault, the housing was too long in front of the handlebars, the handlebar tape was poorly done, and some minor components were misaligned. These issues are minor but noticeable, and for the price, I expected better. • It’s not bad, but I don’t think the 2x is necessary (at least for me). I am yet to shift out of the bike chain ring. Personally, I would not hesitate to buy this bike. While some might argue that the price is higher than comparable models, Salsa’s reputation for quality gravel and mountain bikes is well-deserved. From my research, they invested significant time in developing their e-line, and it shows. I hope this review assists you in your decision-making, and whichever route you choose… ride on!

Mahle X35 motor
10 months ago
I have a Cannondale Quick Neo (no longer available)with the same Mahle X35 motor. The Mahle is wonderful. A feature I didn’t discover until a few months was the Mahle app’s ability to link to my Polar chest strap heart rate monitor. It then has an automatic transmission! The boost switches automatically based on my heart rate. I still get a great workout, but the hills are leveled. Lots of user settings for motor profiles and boost levels. I also have the extender battery which doubles the range.

After 6 months: solid 4½ stars and some complaints
3 months ago
I'm broadly quite happy with this purchase, which is really close to the ideal bike for me. The good: comfort on the hoods, more than enough power assistance for my needs, a decent frame with lots of lugs for accessories, high quality Shimano drivetrain and brakes. The bad: some loose parts from the factory, paint that chips if you look at it funny, some issues with the control hardware and software. The shrug: I was pretty sure I wanted a 2X drivetrain but in six months of city riding I don't think I've ever used either extreme of the gearing. Turns out I might have been okay with a 1X drivetrain, although I'm happy with the upgraded GRX brakes that I wouldn't have gotten with the 1X Apex version of the bike. I'm mostly riding it as a commuter on the occasionally terrible streets of DC. I outfitted it with fenders, a rear rack, and a cage (bought at REI), as well as some hardwired lights I ordered elsewhere. Almost immediately after riding it out of REI I had to return to get one of the brake hoods aligned again, as it hadn't been torqued properly. I also lost both bar end caps in short order. The REI tech who helped me said that the cockpit arrives assembled from the factory and all they do is attach it to the stem, so both things seem like a factory fit-and-finish issue. (Arguably REI should have caught the loose brake hood before delivery, mind you, but the bike shop was slammed after a member event so it seems forgivable). Within the first week there were paint chips in places I certainly hadn't touched the bike with anything heavy. I understand now this is common with Salsa paint, but it was disappointing. I'm really happy with the rear hub Mahle motor. I wanted a bike that felt like a normal bike, just with a little extra juice when I needed it due to autoimmune-related fatigue and exercise intolerance. I didn't want something that weighed a ton. The good/bad news is that early on before I figured out how the power controls worked (bad) I rode six miles with the assistance completely off and I was fine, if a little more tired than I expected to be (good). Then I figured out the assist had been off and learned how not to repeat that mistake. I've since bought a bike computer that makes the current assist level super obvious. I mostly keep it on 20% assistance around town, bumping up for a couple hills I climb regularly. At low assistance levels I don't notice the motor cutting out. On a couple occasions when I've left the assist on full blast and gone downhill enough to get near the 20 MPH cutoff, I have finally experienced the thing people complain about — it's on, and then it's off, and there's no smooth transition between the two states. At low assistance levels, or at low speeds, you'll never encounter it. If you're trying to keep up with speedy friends and you have the assistance dialed up, you'll probably feel the power cutting in and out and it might bother you. For my needs I'm fine with it. On the low end I have never had any issues getting up to enough speed for the assistance to kick in. I don't feel any lack of low end torque, which is a common criticism of hub motor bikes. I feel this complaint is overblown, but maybe I'm just so used to acoustic bikes that I'm making up for shortcomings with my own torque and just not noticing. Overall I'm very happy. The handling is great for my needs, I get more than 80 miles per charge on my usual power settings, and the geometry is a great fit for me. If it had better paint I might have given it 5 full stars.

Great ebike! (With a few caveats)
1 year ago
I purchased this bike -- and, unfortunately, returned it after a couple of short test rides. My return was, in part, due to ME -- I, sadly, found that an elbow injury was triggered by being on a drop bar bike again where it's not on a flat bar bike. But the other primary reason I returned it was due to a feature that I thought I could install on the bike and found was actually not available after the fact. Let's start with the good: 1. The weight! It's a very lightweight ebike which is quite possible to ride with the power OFF and still feels like a "regular" bike. My first ride on it was that it felt like the old road bike I used to love with the legs I had 10 years ago! 2. Whether you consider it a "feature" or not -- it's a class one ebike, which is what I wanted. Meaning that where I live it is legal to ride on multi-use trails. 3. Mahle, like Specialized, has a range extender battery which is fairly lightweight so you could use multiple ones to extend your ride. 4. Like Salsa bikes, it has lots of mounts for things, including three-back mounts on the fork. 5. There are not too many ebikes with a 2x drivetrain. I didn't realize how much I missed that:) That's one of the reasons I ordered this bike vs the flat bar version (which, unfortuantely, REI does not currently stock). 6. Easy to install a dropper post. HOWEVER, though it says it's "internally routed" you will actually need an EXTERNAL dropper on this one as it's only internally routed in the sense that there's a hole in the top tube so you don't have to velcro any external cables onto your frame. The things I didn't like: 1. The drop bar versions of the Confluence do not include any power level controls on the bars. I found that as of May 2024, the Mahle e-shifters are not compatible with the current iWoc unit -- to use them will require a new head tube unit which will be availble, perhaps, in September. I was told (by Mahle) that they were compatible before I purchased the bike. To their credit, they offered me the new controller and e shifters, when available, if I did keep the bike. 2. A couple of the mounts have limited insertion for screws due to the battery placement -- so no mounts under the tube. 3. Based on my few short rides with the bike, I think I prefer a mid-drive motor vs a hub motor. However, I'm considering, again, testing out the flat-bar version of the Confluence which has bar controls as, overall, that bike would likely work better for me than this drop-bar version. 4. I don't really love the placement and ease of use of the power connector as compared to Bosch and Specialized ebikes I've used.
