EG is an electric bicycle brand that balances price against power and features. Some of the hardware they choose is at the basic or entry-level end of the spectrum, and I found that the stem on this particular bike felt a little loose, but the bikes are more affordable and work fine for recreational riding. Recently, EG upped the power and speed on a couple of models, including the step-thru Maui 500 EX here, in response to requests from shops like the one I was visiting. Cruiser bikes offer a relaxed, upright, and comfortable body position compared to hybrid or city bikes. They tend to have larger handlebars, fatter tires, more comfortable seats, and even suspension… It’s a great combination for people who might not get out as much and just want to hang out with friends and be able to spot traffic vs. crouching down and pedaling hard and fast. In fact, if you look at the pedal position on this ebike, notice how they cranks are mounted forward, towards the handle bar vs. directly below the saddle. This positioning allows riders to get decent leg extension forward but still reach the ground for stability when stopping, all without dismounting the saddle. The really interesting thing then, is that you can still go fast on this bike. It’s relaxed but still very capable and fits into the Class 3 speed-pedelec category. Compared with older iterations that had rear rack-mounted batteries, the new Shark pack is lower and more stable. This frees up space for gear (up to 55 lbs of it) at the rear and reduces frame flex. Unfortunately, it also clutters the downtube and may expose the battery to an occasional kick during mounting or dismounting. Some of the wires that run to the controller, battery, and motor are more exposed on this bike but it is a purpose-built electric bicycle which means the frame was designed for added power and speed. There’s only one size but the seat can be dropped fairly low and the handlebars swivel back. I love that they included a chain cover for ladies who wear pants, skirts, or dresses when riding because it’s no fun to snag or get grease on nice clothing… and the fenders also help with this, but I found that they were lower quality and rattled around and came loose easily. Perhaps one final thought on safety, the white walled tires and silver or grey frame color options will be more visible than all-black but aren’t quite as good as reflective tires. And you get LED lights here but they run off of independent AAA batteries vs. being wired in to the main pack. This can become a chore to remember when starting and stopping. And if you forget, the lights may have drained to zero the next time you head out for a ride.

Driving the bike is a 500 watt planetary geared hub motor mounted in the rear wheel. It is made by Dapu which is one of the higher quality hub motor manufacturers, and I found it to be quite powerful. Sometimes in the ebike space it’s difficult to tell how a bike will perform just based on numbers because there are extra settings that can be changed by the manufacturer. A 500 watt motor with low Amperage won’t feel as zippy as it could. So to me, the EG motor felt very zippy and capable. Almost too zippy at times, especially in the highest of the five levels of pedal assist, because it goes from completely off to full-on. Unlike some of the fancier, more expensive electric bicycles, this one uses a cadence sensor only. It doesn’t measure how fast the bike is moving or how hard you’re pushing on the pedals, just that you’re pedaling at all. My recommendation would be to always start with the lower levels of assist, the bike seems to automatically jump to level two when it is first turned on and this is okay. A neat feature of this product compared to most others is that it also comes with a throttle mode. This is much smoother because it measures how far you’ve pushed the throttle. During the video review, I tried to demonstrate this by starting out with a very slow and gentle push on the trigger throttle which resulted in very limited power and a lower speed. The throttle is always active on this e-bike as long as the display is on. You can arrow down to level zero in the display to completely shut off pedal assist and only use the throttle if you’d like. Considering that the EG Maui 500 EX weighs about 56 pounds, it’s really nice to have access to instant power when you’re starting from rest. As someone with a sensitive left knee, this throttle mode is very handy… but it could also get bumped and send the bike rushing forward (so be careful when you’re getting off the bike or loading the bike… always turn it off first).

Powering the motor and backlit display panel is a large sized Lithium-ion battery pack that mounts to the down tube. You can charge it on or off the bike and this is useful for those times when you’ve got to park outside or want to top off the charge at a friend’s house or work. The pack weighs about 6.6 lbs so removing it also reduces the overall weight of the bike, making it easier to move or work on. You get a powerful 48 volt 10.4 amp hour capacity and I was told that the cells inside are made by Samsung. This pack falls under the year-long comprehensive warranty that EG offers and I love that they sell through shops because this means you can do test rides and get subsequent service more easily. While I do wish that the pack was mounted under the top tube (perhaps sandwiched between it and the downtube) I feel like it’s mostly out of the way and offers a much better experience than the older rear-rack style. The battery is often one of the most expensive and sensitive parts of an electric bike so plan to store yours in a cool, dry location and keep it at ~80% full when not in use.

Powering the bike on is very straightforward and even though I feel that the display looks generic and cheap, it did a fine job. Just hold the middle button on the left control pad for a second and look for the display to flicker on. It shows your speed, trip distance, assist level and battery charge level. You can arrow up from 0 to 5 for increased power and speed and you can hold the up arrow to turn on backlighting. As someone who occasionally rides at dusk, I like that you don’t have to turn backlighting on because sometimes it can seem bright and distracting. I don’t always need to know how fast I’m going or what level of assist I’m in, especially if I’m riding in level zero and just using the throttle. For this type of situation, the display used here is great. Now the downside is that the display and main battery are not connected to the headlight and taillight. These parts are decent quality, they just aren’t “wired in” which means you have to reach forward and back to turn them on or ideally, do it before you even get onto the bike. And then, do it again when you get off. The display panel is large, easy to read, and can swivel forward and back to reduce glare, but it is not removable. Consider placing your helmet or a glove over it to reduce sun exposure and keep your fingers crossed that it doesn’t get bumped or scratched at a bike rack. The button pad to navigate through the display doesn’t look as polished as some of the branded King Meter displays I’ve seen on other bikes… but it has the same layout and buttons. It is rubberized, easy enough to reach, and can be used without looking down once you get the hang of it. There are only three buttons after all :)

For me personally, this ebike sends mixed signals because it really isn’t that cheap… but it delivers a lot of power, speed, and accessories for the price it hits at ~$2k. Some of the parts are basic, but they look good enough and for example, the eight-speed drivetrain is three steps up from entry-level in the Shimano line! And yet, the adjustable stem did not feel very solid, the fenders seemed very close to the wheels, the wires aren’t as hidden as they could be, and the mechanical disc brakes are just okay vs. hydraulic (especially given the weight of the bike if you’re going fast). If you need some extra power or simply enjoy going fast, this would be a good choice and it really is unique, it just makes some compromises. So many electric bikes are foregoing throttles these days and optimizing their pedal assist sensors. You get a more basic pedal assist sensor with the EG Oahu but that throttle really works great. The suspension fork and longer bars added a lot of comfort to my ride but there was no lockout on the fork for smooth sections so it sort of changed how pedaling felt with a bit of bobbing. The tires are okay but I’d probably put some Slime in them to help deal with punctures… and eventually, I’d upgrade to something with a puncture-protective liner. Sam told me that he has done this for several customers, completely removing the fenders and adding larger 26″ balloon tires like the Schwalbe Fat Frank Balloon model that has a reflective stripe on the side and comes in three colors. It’s easy to identify shortcomings on a value-priced ebike but trade-offs have to be made. From my perspective, EG has been doing a great job of working with dealers and providing customers with a solid option at a good price for several years. Yeah, I’d probably replace the stem and get some tire upgrades… I’d also be careful with pedal assist, and I’m sure I’d enjoy the bike. They do offer a high-step cantilever frame called the Oahu 500 EX that’s a bit stiffer lengthwise but not as easy to mount. I like that the Maui looks unisex vs. bright pink because I would feel comfortable riding it or the high-step as a man. Anyway, big thanks to EG for partnering with me on this review and answering all of the detailed questions I had about the specs and of course, to Sam Townsend for allowing me to swing by his shop in Fullerton California and get his perspective on camera. He’s a larger guy who has ridden these bikes further than I have and it’s great to get his opinion.


  • One of the few high-speed cruiser style electric bikes I’ve seen, you can hit ~28 mph and the motor is very strong (even Sam thought so and he weighs ~250)
  • Comfortable tires, suspension fork, and oversized cruiser handlebar make it easier for people with back and neck pain… especially at higher speeds
  • Compared with the EG Oahu model, the Maui is easier to mount and stabilize when stopped, the frame is a low-step and provides a relatively low minimum seat hight
  • Considering you get fenders, a chain cover, a rear rack, LED lights, a higher capacity battery pack, and dealer support, I feel like the price is pretty good
  • The bike offers pedal assist and throttle mode which is handy for people who need help starting but want to pedal for exercise, I appreciate the motor cutoff in the brake levers for safety
  • The motor is made by Dapu and the battery cells are from Samsung, these are higher quality manufacturers and I’d expect them to hold up better over time, EG offers a one-year comprehensive warranty
  • As someone who commutes and wears pants frequently, I appreciate the longer fenders and chain guard, this would protect your pants or dress from getting wet and dirty
  • The controller box is positioned behind the seat tube and is protected well by the back fender, it has a metal case and just seemed well built
  • Rather than mounting the pedals directly below the seat, they are positioned a bit forward which allows for leg extension while pedaling but also the ability to put your feet flat on the ground without hopping out of the saddle when stopped
  • Their new cadence sensor is super small and likely won’t get bumped out of place as easily as the older designs


  • The frame flexes a bit more than the Oahu but isn’t too bad compared with other cruisers that have a rear-mounted battery pack, you can tell they reinforced the tubing to keep it stiff and stable
  • The lights are wonderful to have for safety but aren’t as integrated and convenient as if they were wired directly to the main battery pack, you have to power them with AAA batteries and they could run out easily if you forget to turn them off after the ride
  • Despite being mounted towards the middle of the frame, this battery design is a bit more exposed than some others (which have packs positioned between the top tube and downtube),
    the pack is higher and further forward, it could get kicked more easily when mounting or dismounting
  • It’s only available in one size but the bars are adjustable to dial in fit, unfortunately, the adjustable piece can come loose over time so you might want to upgrade it to a solid stem if you notice an issue cropping up
  • Some of the hardware is just cheaper, the tires look nice but don’t have a reflective sidewall or puncture protection, the drivetrain is closer to entry level, the suspension fork doesn’t lock out, and the display panel and button pad aren’t as refined (the casing looks cheap)
  • The display panel is not removable so it could fade over time if left in the sun,
    you can angle it to reduce glare and it is backlit for use at night
  • There wasn’t room on the frame to add bottle cage bosses but the rear rack offers up to 55 lbs of cargo support and you can get trunk bags like this with bottle holsters
  • The bike can sometimes feel too powerful and the motor activates in an on/off way vs. smooth rising and falling because it uses a cadence sensor, you can lower the top speed by riding in the lower levels of assist but the motor is still abrupt
  • The bike is on-par with other cruisers in terms of weight (especially given the accessories it has) but the battery does not have a built-in USB charger like the older Dolphin pack offered, the new Shark pack is slimmer and sleeker looking
  • Sam said that his shop, the Electric Bicycle Center in Fullerton, regularly takes off the fenders and puts on larger tires for an even more stable and comfortable ride
  • The cables aren’t all internally routed so there’s a bit of clutter on the frame,
    the kickstand isn’t far back enough to stay out of the way when you back the bike up (the left crank arm can collide with it)
