3 years agoI would be interested in this bike, especially because it has a Yamaha motor. My experience with my Yamaha PW motor in my 2016 Haibike Allmtn Sduro Fullseven has been excellent. In five years and 14,000 miles nothing has gone wrong with the motor or the electrical system, including the battery and the controller.
Compared to the Bosch motor that comes with the Tern HSD S+ (which I bought for my girlfriend), the Yamaha motor is much stronger, especially climbing hills. I understand that Bosch makes a stronger cargo motor (available with the Tern GSD), but I have not tried it.
I only wish the Momentum Pakyak had front suspension and that it weighed less.
ReplyCourt
3 years agoHi Alberto! Thanks for the testimonial about your experiences with the Yamaha and Bosch motors. I think the Pakyak was really well thought out, I especially like the battery design here vs. some of the Giant mountain bikes I’ve reviewed recently. Comfort wise, even without suspension, the Pakyak felt pretty good. I think the added weight reduces vibration and shock, the tires were wide and squishy enough that I felt comfortable on gravel and going over the curbs (video is uploading now and should be available to watch shortly so you can see what I mean).
ReplyDewey
3 years agoI’m surprised Giant went with a Class 3 speed for their cargo ebike. It will surely limit appeal to parents living in and riding on street in the suburbs. Where I live in Arlington, VA, the county and Park Service Regs permit only Class 1 & 2 to ride on local paved trails, while over the river in Washington, DC, it’s even stricter as Class 3 ebikes are not permitted to ride on-street bicycle infrastructure including PBL’s. I hope Giant’s dealer software can reduce the top speed to Class 1 20mph?
ReplyCourt
3 years agoHi Dewey, that’s a great question! I asked the marketing and product folks at Giant / Momentum for some feedback and they said “No it is not possible to govern the max support speed nor technically change its class system from Class 1 (20mph pedal assist) to Class 3 (28mph(45kph) pedal assist). However, in the RIDE CONTROL APP the customer can de-tune each modes support % level to essentially slow themselves down with motor support.” I hope this helps! I was also surprised about the Class 3 setup, but think that it’s a neat option for people who want to use the highest assist and shift gears to make the bike go faster. I think it’s still a fairly intentional action vs. always going fast, if that makes sense ;)

3 years agoThis strikes me as a good competitor for the Benno Boost, which I was planning on getting next year but now I’m not so sure. Really the only thing I can think of that the Boost has over this is that it is close to 20 pounds lighter and maybe 5 inches shorter. The Benno Boost I tried out was a lot of fun to ride, I wonder if the Pakyak, also having 24 inch tires, is fun to ride?
ReplyCourt
3 years agoHi Rick! It’s funny that you bring up the Benno Boost because a friend and I were discussing the Pakyak E+ recently and made a similar comparison. I like the speed pedelec aspect of the Pakyak E+ for those in the United States. It’s nice to have two completely different drive systems here (Yamaha vs. Bosch), and I like the accessories that both bikes offer. Benno is a cool company, the guy who founded it also created Electra before Trek bought it. I feel that both Momentum and Benno are high quality brands.
ReplyChacaloski
3 years agoBruh I tried this bike this week on Tuesday with the guys from Spokes Etc at Belle View location in Alexandria VA and was really impressed with the speed for a cargo bike. I was not able to test out the bike on a steep hill that was next to the shop cause there is an really dangerous intersection with phone zombies behind the wheel, but I would love to see another vid from you riding a steep hill test to see if this is worth it. I feel like they could have gone with at least 7 gears but they chose 5.
ReplyCourt
3 years agoI’m glad you had fun with the bike! Yeah, a couple people have mentioned that it would have been nice to see a hill climb. Your point about the limited gears (and gear range) is understandable. I think they had limited options on which hardware to use… but overall I think it works great. To me, it felt very powerful and responsive, I was surprised actually. I suspect that it will climb well and haul a good amount of cargo, on par with something like the Bosch CX motor. Perhaps someone else will chime in here with some real world experiences.

3 years agoHow do you like this bike compared to the Xtracycle Edgerunner eSwoop?
ReplyCourt
3 years agoHmm, if cost was equal I’d probably get the Momentum due to higher speed and refined build… but! I have so much respect for Ross and the Xtracycle company. I think that one is lighter and has so many cool accessories. I loved the Pakyak E+ but prefer the Xtracycle brand and would love to see their latest and greatest to really make the decision.
ReplyBrian
3 years agoThanks Court!! What about the Tern cycles compared to the PakYak E+ and the swoop? Thanks again
Zach
3 years agoThanks for the once over on the Momentum PakYak E+ and for your opinions on what is great and what is not so great!
One thing that I didn’t hear you mention, nor can I find any info about it elsewhere, is where does one attach a water bottle cage? Is there a spot for one?
Cheers!
ReplyCourt
3 years agoGreat question Zach! This is something I’m always looking for with ebikes, since the battery design might limit traditional bottle cage mounting options. I found that the Momentum Pakyak E+ does have two bottle cage mounts on the front rack (near the corners in a vertical position). It’s a pretty good design because water won’t leak out and they are easy to reach while riding. Alternatively, you could buy an SKS Anywhere Adapter that uses straps to mount on a seat tube or other tubing of the bike frame :)
ReplyZach
3 years agoHey Court,
Thanks for the quick reply and also for the info. I went into a local shop today to have a look at the Pakyak and neither I or the store employee noticed a spot for a water water bottle. I am going back tomorrow to test ride it after the change out the bar stem, installing one that is higher and is a little more forward than the original as I am a tad tall with long arms, so I will have a look at the rack again.
Did you happen to notice that there is a gap at the top of the battery cover when it is installed and locked? The gap is between the battery cover and the frame? Both Pakyak bikes that the local store here has have gaps. We tried to get it to secure flush, tight, but we were not successful.
Since you first review has anything changed for you in regard to the Pakyak? Is there any other brand that has a new cargo bike out that you might like better? Thanks again for answering my questions and for your time, I appreciate it.
Cheers!
Zach
3 years agoHi Court! As before, thanks again for taking the time to answer my questions and for the info you provided.
I went back to the local bike shop here and test rode the Pakyak again after the shop changed out the handlebar stem. They replaced it with a taller one as the stock stem is too short for me. I am 6’4″ with long arms! They had also maxed out the seat post but with this it was still not comfortable. A mechanic there then suggested that they also swap out the handlebars for one with more of a rise and a tad wider. This ended up working very well for me. The only thing is that the post was extended to the max height and as such then had a bit of play and then with the slight suspension it ended up being too short but just by a small amount. The mechanic then suggested removing the dropper post and going with a rigid post that is longer given that I will be the only one riding the bike. He also pointed out that taking a bike of that design down a very step decline, where one would want to be able to lower the post quickly, is not likely as it would be a heck of a ride!!
I heard back from Giant and they said that the gap with the battery cover is normal and won’t affect anything. I disagree and it’s just enough of a gap that dirt and mud will likely build up inside the frame and around the battery. I am going to investigate further, to see whether or not the battery mount inside of the frame can be moved back into the frame a bit more. I had a look at your video review and the battery cover appears to be flush with the frame without any gaps.
I did check out a Tern GSD, however it did not work for me and my wing span. It’s a great bike but so much of the design is the same as some of the other ebikes that can be found on Alibaba and Aliexpress. The differences are mainly with the drive train, brakes, etc. After riding the Pakyak I much prefer the 24″ wheels on it over the 20″ wheels on the Tern but that’s just me! Rad Power bikes are okay but not the same quality of the Pakyak or Tern which I am sure you know all too well.
I won’t take up anymore of your time. Thanks again for your input and for your webapge. The comprehensive reviews with videos are fantastic and are very well done.
Have a great 2022 – keep safe!

3 years agoCool! Thanks for sharing the details about your height. It sounds like they suggested all of the same things I would (stem, handlebar width and rise, seat post swap). I definitely see how a taller rider would benefit from a sturdy frame and the taller wheels. I agree that Pakyak E+ is a strong contender on the shortlist. The challenge with custom builds like this is the potential for battery gaps and other things that just aren’t quite 100% perfect. Interesting that my video showed a tighter fit with the pack. Not sure what the deal is there… Thanks again for the encouragement with EBR, I enjoy helping out and feel that eBikes are a nice area of work to focus on. I hope you enjoy whatever bike fits (or that you make work) and that it holds up well for you. Reach out anytime Zach.
