Written Review

To run the forums, host the website, and travel, I charge a universal service fee for my reviews. This in-depth review was sponsored by Surface 604 Bikes. My goal is to be transparent and unbiased with you, this video and writeup are not meant to be an endorsement of Surface 604 products. I welcome your corrections, additions, and feedback in the comment section below and the Surface 604 electric bike forums.

Observations:

  • The price increased from $1,890 to $2,099 for the latest version of the Surface 604 Shred. The paint design was updated with new decals and the steering tube got slimmer while the top tube got more angular in design. The top tube has been lowered a bit more to make the bike easier to approach and stand over and they’ve moved to a rigid stem with steep 45° angle for a more upright body position
  • The torque sensor was relocated from the bottom bracket to the rear wheel, which performed just as good if not better than before, and they added wiring for an optional rear light to be powered by the main battery vs. being independent
  • Surface 604 offers a bunch of great add-on accessories that are optional and add to the price including custom fitted fenders, a rear rack with pannier hangers as well as slats to support a trunk bag, and an optional suspension seat post with shim (adapts 30.4mm to 27.2mm)

Pros:

  • Given the $2.1k price point, Surface 604 hasn’t skimped on quality or durability too much, the headset and bottom bracket still use sealed bearings that won’t rust or creek as easily, they chose great pedals, a solid drivetrain with wide 11-34 tooth cassette, and Velo branded locking grips
  • Given the higher potential top speed and heavier build of this ebike (especially with suspension seat post and rear rack options) the 180mm hydraulic disc brakes with long four-finger levers and motor inhibitors are perfect
  • I like that Surface 604 is offering two battery size options for this bike, you can spend a bit more money to extend range if you like riding faster or plan on carrying heavier loads, both packs are positioned low and center on the frame for balance and look pretty good
  • It’s rare to see an integrated headlight on cross country / trail mountain bike like this, but I like the light that they chose because it’s bright and feels solid, it could come in handy if you add a rear rack and use the bike around town during the week (I love that the frame has rear rack bosses and that they pre-wired it for an optional rear light)
  • The suspension fork on this ebike looks good and has some decent adjustability (lockout and preload), but weighs more because it uses springs vs. air and has steel stanchions vs. anodized alloy
  • I love that Surface 604 decided to include a kickstand on this e-bike! This will come in handy for those who like to ride around the city or just need an easier way to stand the bike up in their garage or apartment… it’s easy to remove the stand for off-road use to reduce bounce and jitter, they positioned it at the rear of the frame so you won’t get pedal lock
  • I like that the battery can be charged on or off the frame and has a full sized USB charging port built into the right side (which can be used whether the pack is mounted to the frame or not), there’s a second USB port on the right side of the display panel that’s perfect for use with a smartphone or secondary headlight
  • The Shred is unique in that it can reach higher top speeds of ~28 mph (45 km/h) and has a trigger throttle, these are features not commonly found on trail and mountain bikes but they might restrict where it can be used legally because it’s a Class 3 vs. Class 1 in this configuration. You can adjust the top speed in the display settings and remove the trigger throttle easily with the quick release connector if you want to ride as Class 1 instead
  • I’m glad that Surface 604 chose to use a trigger throttle here vs. half-grip twist throttle, because those can be accidentally activated much easier when riding on bumpy terrain, triggers seem to be safer for off-road use because they don’t compromise your grip and stay out of the way
  • The torque and cadence sensing rear dropout hardware worked very well during my test rides, I never felt like there was a delay or that I had to work extra hard (which can sometimes be the case with pure torque-only sensors)
  • Minor pro here, I like the large, sturdy, grippy Wellgo aluminum alloy platform pedals that Surface 604 chose, they match the colors and design, and provide a stable surface to ride from compared to plastic or alloy cages
  • Surface 604 products can be found at dealers in Canada and the USA, but they also sell direct online and offer free shipping, there will still be some setup involved but at least it doesn’t cost a lot extra
  • Both wheels are built with thicker spokes and 36 hole vs. 32 hole to add strength for the higher speeds, off-road use, and optional rear rack. I like that the spokes and rims are black vs. silver but would have liked black nipples as well
  • The hub motor performs very quietly, I could hardly hear it activating in the frame shots from the video review above, some competing hub motors produce much louder zipping sounds, especially under full power
  • The new color display is awesome! It’s slim but very easy to read, it has battery percentage readout vs. infographic 5-bars like many others, the control pad has dedicated buttons for lights and information, it even dims the display when you turn the headlight on… it’s one of my favorite displays out there right now
  • Unlike the prior-year version of the bike, the trigger throttle now overrides all levels of assist (including 0) with full power, so you can zip up hills or catch up to friends without having to click any extra buttons, great job on that!

Cons:

  • The SRAM X5 drivetrain is pretty snappy but the trigger shifter for high gears is one-way vs. two way and there’s not clutch system like Shimano offers on some of their derailleurs
  • The headlight will bounce more on bumpy terrain because it’s mounted to the fork arch vs. the head tube or handlebar, it feels solid enough and I like the beam pattern (it helps you actually see terrain vs. just being seen)
  • Minor consideration, despite the larger 27.5″ x 2.8″ plus sized tires, the hub spacing isn’t boost and the axles are more traditional 9mm front and 11mm rear vs. thru-axles at 15 mm front and 12 mm rear which would provide more stiffness and strength
  • Weighing in at ~57.3 lbs (for the 19″ frame with the smaller 10.4 amp hour battery), this ebike is a bit heavy for a hardtail and I think that comes back to the spring fork, plus sized tires, and more powerful hub motor
  • The prior-year version of this ebike had an adjustable angle stem that was pretty nice! I guess they dropped that part to help save money and because most people put it in the high 45-degree position anyway, I think they still sell that part separately for people who like adjustability
  • Because the battery pack is positioned so low on the downtube, the charging port is located in the path of the left crank arm, and as a result, if you’re charging the pack on the bike, the plug and wire could get snagged or bent more easily
  • The demo model I reviewed did not have a slap guard. I’d probably add a basic sticker slap guard and some cable sticker guards like this just to keep it looking beautiful, but the team told me that future models should have this included so maybe it’s a non-issue? I was also told that future models would have bottle cage bosses along the base of the downtube and a low-rise handlebar vs. straight
  • There’s a little bit of crowding at the right rear dropout because the shifter cable and motor power cable both connect here, try not to let these cables get snagged or bent (like if the bike tips over), there’s no derailleur guard or other protection hardware in place but you could add one aftermarket for under $10 if you wanted, I was told that future versions of the bike should have a derailleur guard included
  • The display seems tough and is easy to read because it swivels a bit, you can interact with it easily thanks to the independent button pad (mounted near the left grip) but you cannot easily remove the display… so it could take sun and rain damage over time or get scratched at a bike rack
  • The control pad is mounted behind the trigger throttle on the left, and I found that it took a bit more flexibility and effort to reach in this configuration, you could always change the order, but then the throttle would be tricky to reach, you could also try to put the throttle on the right portion of the handlebar but then it will interfere with the trigger shifters, maybe a future throttle mount will be narrower so the buttons can move closer… also, I prefer to have the throttle on the right, but it wouldn’t fit there because of the trigger shifters
  • There’s no chain guide in place and the chainring uses standard teeth vs. narrow-wide which would improve chain retention, though I didn’t experience any chain drops during my test rides

If you ride down into Colony farms through Riverview Hospital grounds you can make a nice loop on the Treboulay trail or even cross over the Pitt River bridge and make a bigger loop around Pitt Meadows dikes.

Court, I’ve been reading a lot of your reviews. I am in an area that does not have a lot of bike shops or selection to choose from. I am just a recreational rider, nothing to serious but want the ability to ride on a trail if I want to. Here is the main part of it though. Probably like most I do not want to break the bank for an e-bike until I really know if I am going to enjoy it. I have looked at Trek, Giant, and the Surface 605 Shred. I did speak with Rad bikes and they were very honest with me which I appreciated that their bikes would probably not be the best for me. Here is why, I am an x-athlete that played basketball for most of his life. I am 6’10” and weigh 285lbs. I am pretty much equal from torso to legs. Which bike would you possibly point me towards. Not sure if the mid-drive or the hub-drive makes a difference with my size.

Hi Tom! Well, I’m happy that Rad Power Bikes was honest with you. You’re a tall and heavy dude, which isn’t going to work as well for the “one size fits all” approach that most value priced ebikes go for. I think you’re right to look at Trek, Specialized, Giant and other major brands that offer a range of sizes. I like Bosch motors, but Shimano and Yamaha are good too. The thing is, most of these mainstream brands (which have sizes and shops) don’t offer throttle… just pedal assist. For me, that’s just fine! The highest level of assist is often zippy and fun, and you can go for a trail capable ebike for those occasional mountain rides. For my own very first electric bicycle, I opted for an affordable online product, which I couldn’t test ride or see before purchase… this was way back in 2012, and my experience was disappointing. The bike couldn’t handle trails, it was heavy, and the motor performance was lackluster. So, my buyer’s remorse was more around wishing I had spent more… because I loved riding so much and I knew I was missing out on an even better bike that would be so much more fun and performant. Since it sounds like you’re in an area with few shops, and you’re aiming for a value buy, I recommend reaching out to a shop called Crazy Lenny’s and ask specifically for Len (the owner). Tell him your details, mention EBR, and I’m sure they will be able to find a good product for you. Possibly a BH electric bike (since they have a big sale going). This company has different sizes for some models, they occasionally offer a throttle, and the value is good. However, I think the company is backing off of the North America market because they used to sell more bikes under the name Easy Motion (which I reviewed a bunch) but now are only called BH, and their headquarters moved. So yeah, you might get a great bike but end up with limited support at some point. This is just a possibility, as with any company, but they just aren’t as prevalent these days as Giant, Specialized, or Trek… with Specialized and Trek being my favorites ;) ps. there are many great shops, I don’t get a commission from Crazy Lenny’s and don’t always recommend them, just seemed like a decent fit here. You could also try Propel Bikes in Long Beach or NYC, but they are more premium.

I am looking for a reliable trail-commuter that can handle single track and double track on the way to work. Looking for a class 1 (I think), but want at least decent-quality components that will work on the single track and the bike lanes. Would help to have the option to mount a rack or panier on the back. I’m new to this market and can’t tell whether I would do better on a Volt Enduro, Volt Outback, or something like this Shred. I am not looking to break the bank, I already have a great Mtn bik and fat bike. Any advice?

Hi Heather! I think you’ll get a slightly more dynamic experience with the Surface 604 Shred because it uses a torque sensor. Since you’re already an active rider, this type of ebike will feel more sporty and responsive. VoltBike has great value products, and Rad Power Bikes is a similar option, but Surface has historically taken things one step up with torque vs. cadence sensors. All of these products have twist throttles to help you get going, take a break from pedaling, or just cruise around for fun and catch up to friends without clicking on the button pad to change assist levels. Also, the Surface 604 Shred has rear rack bosses, so you could add your own rack aftermarket. This platform would be a great “dual sport” setup for you, and is the type of ebike I most enjoy. I hope this helps, and I’d love to hear back someday about how you like the bike. You can also ask around in the Surface 604 forums or the help choosing ebikes forum.

Hi! Thanks for your great review. I wondering about the torque on this bike. You talk about 50 nM and the company says 65 nM. I have call a resaler and he told me that they choose a higher speed specific Bafang motor who do have 65 nM. Can you tell me what you think about that? Thank you!

Hmm, that’s a great question and I apologize for the inconsistency. I work hard to get the best information here, when doing these reviews, and sometimes the bike manufacturer will say something slightly different from the motor, battery, wheel manufacturer. Sometimes they will actually get a custom version of a part and that will conflict with my research. Other times, they will use the same part, but exaggerate the spec or even have a different spec printed on it to appear better. There are lots of variables to consider, but my experience with Surface 604 is that they are honest, have good products, and I try to show the real world performance by creating videos. I’d take the company and dealer at their word in this case… even 50nM can be good if you have a range of gears to pedal with. I hope the bike works well for you, and apologize that I cannot provide a perfectly clear answer about the actual torque rating, I don’t actually have a way to test it myself independently… and even then, it could be highly variable depending on if it’s measured at the center of the hub, the wheel/tire, or pedal crank going from hub motors to mid-drive motors. For more feedback and insights on this topic, you could ask around in the Surface 604 forums here if you’d like.

Thank you for the review, and all the hard work you have done over the years. I bought a Rad Rover gen 1 in 2015 because of your review, so it’s nice to see that you are now well-known as the best reviewer on the internet!

I’m wondering: does the throttle stop at 20mph on the shred? Is it wobbly compared to a Rad Rover? The first time I rode a mountain bike after the Rover, it just felt wobbly on thinner tires.

Also: I’m torn between this and the Rize blade. I noticed in the review of the blade that it looked somewhat awkward to pedal, but I love the style/speed/option to have someone on the back.

Are both of these bikes a big difference in ride quality from a Rad Rover? Which is faster, Blade vs Shred, and finally, does the throttle shut off on either the shred/blade at 20mph like most ebikes?

Thank you so much, hope you are well.

All great questions, Cole! I’ll do my best to provide some answers real quick, but it has been a while since I looked at the deeper settings and don’t want to guess and set a bad precedent here. I do believe that the default setup on the Shred is 20mph / 32km/h cutoff in throttle mode, and that’s the same for RadRover and most Class 2 and Class 3 ebikes in North America. Yeah, sometimes you can adjust the wheel size to make the bike go slightly faster than 20mph, but that also changes the speedometer readout, so it’s not easy to tell how fast you’re “actually” going. If you want to know more about these settings, I’d suggest calling Surface 604 directly to ask a customer support rep. I think they’re less shy about sharing unlock secrets for individuals and especially if you plan to ride in private settings or off-road.

Your definition of wobbly might be different than mine, but the Shred did NOT feel wobbly to me. I ride a specialized Stumpjumper with 27.5″ x 2.8″ plus sized tires… very similar to the Shred. My personal bike has thru-axles and boost hub spacing, but the actual ride feel and stability of the tires is similar… and the Shred is a LOT more affordable (which is why they didn’t go with boost, I think). Anyway, I prefer the “nimble” feel of plus sized tires vs. full fat tires, which produce more noise and add weight. I’m a sporty 5’9″ 135lb rider, so keep that in mind. Full 4″ fat tires might feel less wobbly in a way, and they will add cushion comfort, but they also create a weird steering feeling at times, like oversteer on a motorcycle where you have to push away from a turn as the bike starts to take a turn. I hope that makes sense, it just has its own trade-offs.

I really liked the RIZE Blade, but yes it can be awkward to pedal. That thing was powerful, had room for a second rider, looked cool, and the company is very responsive and easy to work with (at least for me). The downside is the wider frame and no saddle height adjustment. Rad Power Bikes nailed this with their RadRunner, and is worth considering also… but no suspension there.

My personal favorites are the full sized RadRover and Surface 604 Shred, followed by the RadRunner if you want to pedal, or the RIZE Blade if you are more into scooter throttle action and like the pegs setup. All great bikes! I hope this helps ;)

Hi Court, Thanks for the your great, detailed reviews. I am putting my mountain bike aside and trying to decide on my first electric bike. I will be making a daily 20 mile urban round trip commute to work with it and will occasionally use it for casual off-road riding. I am looking at the Shred, Magnum Mi6, and the Aventon Level. I really just like the styling of the mountain bike better than the commuter bikes.

I am 6’3″ so I do want a frame that will fit me. Any advise on these 3 or another that you really like? -Chris

Hi Chris! I’m with you… I like the mountain bike style, and the comfort of their usually-larger tires. I also occasionally go off road, so it’s nice to be ready for that with sturdier hardware and treaded tires. Some people don’t love the buzzing sound, but I find that it wears down and isn’t so noticeable over time ;)

In any case, I like the order you ranked these in your list. Surface 604 is a favorite of mine, because of the style, torque sensor, and slightly upgraded parts. Magnum is tough to beat, especially in the US with all of their dealers. Aventon is awesome in terms of price, but if you’re ordering direct, I hear it can require more time and energy to build. They also have dealers, so it’s worth looking into in-person if you can. Given your height, it would be great to see and try all of these in person, but that could be difficult depending on your location. The Shred has a nice tall stem, and you could get a longer one if you wanted. You can also slide the saddle back to increase reach, and raise the seat post to the max recommended point (or get a longer seat post, like a Thudbuster ST long version). Honestly, I think all of these bikes are setup as “average size” and you’re towards the upper limit, but they should do alright. The alternative is to incease your budget and get a premium ebike from a big brand like Trek, Specialized, Giant etc. which usually have 4+ frame sizes for each bike model.

I hope this helps! I’d love to hear your thoughts once you choose one, and actually test ride it for a bit :D

Hi Court. I have a new Surface 604 Shred from 2020. The screen is not showing advanced settings anymore. Surface is telling me that it had a hard program and went to the soft program. I told them that the manual is showing how to change the advanced setting. The advance settings were on the screen for about two days, and then gone. I would like to k now if anyone else with this ebike is having the same problems?

Hmm, that’s so interesting David! I wonder if the battery drained completely or something else triggered your display to revert back to a different base version of the software. I have not seen or experienced this sort of situation before, but perhaps someone else on here has and can give you some feedback. You can also post in the Surface 604 ebike forums about it :)

Hi Court,

You cost me some $$$ with this great review – I have a Shred on order!

I really like that Surface604 offers this somewhat more tame version of an eMTB – It seems most manufacturers push the envelope on the very best mechanicals that many of us will never take advantage of, nor really need.

I strongly believe that a bike built for rough use will also pay off with lasting durability for those of us who only ride the green and blue trails, and use it for everyday riding.

I especially liked your last “Pro” bullet point about the throttle allowing full speed in any assist level on the 2020 model. My current entry-level ebike’s pedal assist doesn’t work well and I’ve gotten used to riding without assist and augmenting my pedaling when needed with a blast from the throttle. I was worried I might lose that fun and battery-saving functionality!

Anyway, thanks for the honest appraisals of all the bikes you review. I thought you might want to know you helped me make a decision.

All the Best,
Audrey
