Written Review

The ProdecoTech Mariner 7 is a folding electric bike that costs significantly less than competitors but takes a hit on weight, drive mode options, frame balance and in-person support. All ProdecoTech electric bikes cost less than competing brands because they are primarily sold online, bypassing a physical bike shop outlet. This savings is passed on to the buyer but it also means you may not have a chance to test ride the bike or get maintenance support as easily when the bike inevitably needs repairs. You’ll also have to build it yourself the first time. Still, with a 2 year warranty on all parts including the battery pack this could be an efficient way to step into the world of ebikes.

The motor driving the Mariner 7 offers 300 watts of power with a 500 watt peak and it’s geared meaning you get more torque. This is fairly standard for ebikes where 350 watt geared hub motors have been the most popular choice for full sized offerings. Given the frame size and reduced torque here, this bike is probably ideal for riders under 200 pounds.

The battery pack fueling that hub motor offers 38.4 volts of power and 9 amp hours of range. Again, fairly standard offering and enough to power the bike up to 35 miles in perfect conditions. The cell technology is Lithium Iron Phosphate which provides more cycles than other Lithium-ion types but has a lower energy density meaning in order to reach the 345 watt hours this pack delivers, it ends up being heavier. And this is where the real trade offs begin…

It seems to me that one of the primary benefits of any folding electric bike is the ability to fold and store it. With the Mariner 7 this action becomes more challenging due to the overall system weight. This folding bike weighs nearly 50 pounds while other competing offerings weigh closer to 40. This starts matter when you’re trying to the bike down in a boat compartment or up in an RV closet. Thankfully, the battery pack is removable so this challenge can be somewhat mitigated. Please just be careful when storing this bike so as not to hurt your back.

The ride quality of the Mariner 7 is acceptable. The pedals are plastic and therefore not that stiff. The weight of the battery is elevated high off the ground and all towards the rear which makes it a bit less stable than mid-frame designs but the inclusion of a built in rear light is a nice touch. Since the hub motor is built into the front wheel, that actually helps balance out the weight. I appreciate the seat post shock and idealism of the front shock but honestly, the travel is so short and the springs so stiff that it was hardly noticeable when I rode. The bike could save weight and would ride nearly the same without a front shock of this quality.

Aside from the weight and balance concerns with the Mariner 7, the lack of pedal assist also gives me pause. While this isn’t the only “non pedal assist” electric bike out there, it doesn’t include a cruise control setting which means you’ll need your hand on the grip shifter at all times in order to keep the assist. It’s one of the sacrifices you make for that lower price point. I think of this and other ProdecoTech bikes as entry level scooters. The battery is durable, the components and frames are mid grade and the system works, it’s just less refined. Compare this bike with the EZ Pedaler F300 that weighs less and does include pedal assist but costs $600 more or the IZIP E3 Compact that weighs over 6 pounds less, keeps the battery weight much lower and also offers pedal assist for $1,899.


  • One of the cheapest folding electric bikes available
  • Battery pack is removable and features a built in rear light
  • Fantastic 2 year warranty, free shipping for fixes in the first 30 days
  • Seat post shock smooths out the bumps but don’t lift by the seat as the shock may become loose or break
  • 300 watt geared motor offers good torque and power with 500 watt peak output
  • Oversized disc brakes offer great stopping power
  • Aluminum bash guard protects front chain ring when folding and storing


  • Challenging to find and test ride in person, mostly sold online
  • Battery tends to be heavier due to lower energy density of LiFePO4
  • Battery is positioned high off the ground creating a less stable ride
  • Overall weight of bike makes it less convenient for stowing
  • Frame components are mid-grade, twist throttle is basic, pedals are soft, front shock hardly works
  • No magnets or other fasteners to keep the bike in folded position
  • Can’t mount anything on top of the rear battery pack, also won’t work with panniers

@america94 I have the Heavy Duty Kenda tubes purchased for replacement you mentioned but.. when I got a nail in my tire, I had it patched. I know some people say change the tube when you get a hole but I've put on almost 500 miles since with no problems and now likely to patch vs replace (knock on wood). My tire tread is showing little wear and still running well at about 1200 miles.. (mostly road miles & higher psi). I have picked up some replacement tires from Vee that were not cheap (from the USA and has a flexible bead) that gives the option to go tubeless when replacement arrives. I think George had some tires for 20 x 4 (Kenda's) on the website for a short period of time around $80 a tire so... I think it is better to go with a more expensive as opposed to cheap tire. My thought is that the factory tires on the Volt bike Mariner (Kenda's) are quite decent ones.. but perhaps I have been lucky.

Here is what I've been able to gather from various sources for my Voltbike Yukon 750 (maybe same for the Voltbike Mariner?). Hopefully someone will be able to add to it:

S7 - (km/mile)

bL1 - backlight brightness display (3)

OFf - auto time(min) display off (5)

W d - wheel diameter (26)

bU0 - voltage set (48V)

PSd - password (1919)

SPL - speed limit (45km) - gov cuts off at 32km

CUL - MAX Current Limit set (default 15A)

HAL - Magnetic Pole numbers of speed sensor (default=1. Use Unknown ???)

ASs(AS5) - 1-15 ??? # of Cadence magnets?

Hd6 - sets the throttle to 6km/h; 1=ON, 0=OFF (default 0)

HdP - toggles the throttle power/current level to match the PAS level. 1=ON; 0=OFF (default 0, full power independent of PAS level)

PAs - levels of assist (set to 0-9; default 1-5)

thomas what brand of scooter lift is that?

i was thinking of something like these dirt bike/atv lifts

or maybe this type

then mount one of these bench stands on a flat plate welded onto a pipe that slides in another pipe with holes for a pin so you can adjust up and down

flat plate on the bottom of the pipe and bolt it to the motorcycle lift

most of these lifts weigh about what my ebikes do so hoping it would not tip over, but would have to play with it
it could also be strapped down on the opposite side to stop it from tipping

if you mounted something like i described onto that scooter stand do you think it would tip with a 65lb ebike on it?

what i have will work but a setup like this would be much cleaner and smaller

i totally get what you are saying about the smaller folding bike
love riding my rad rover and all my fat bikes but do NOT like having to lift them onto the car rack much less the bike stand

this is a lot of the reason i bought an enclosed trailer with a ramp and had it modified to haul the bikes
that and having to stop if it started raining and covering/strapping down covers etc

but my prodeco mariner seems totally easy to lift and manage with the battery off, really light compared to the others

i hope the ebikes get lighter in the next several years

• Both their tones are very good
• Large bell's volume being louder
• Designed to capture cables
• Seem well made

Voltbike Mariner and radmini are both great options

I do not know the answer as to whether you can pedal past 20 mph on the mini since I have never tried to do it
but think you can, post on the rad power forum and someone will answer you I'm sure

I would imagine both of these bikes are heavier than the one you had stolen
But the fat tires are awesome

Sorry about your bike, that sucks

APT Intelligent LCD (800S) as the Mariner...
I believe the HD6 parameter sets the throttle to 6km/h; 0 for off and 1 for on. HDP toggles the throttle power/current level to match the PAS level (1 for on) or off (0) for full power independent of PAS level.

I would like to know what ASs (or may be it is AS5) does. Input choices are 1-15 so I'm wondering if this parameter is supposed to match the number of magnets on the bike? Yukon 750 has 12 magnets near the pedals.

Of course still curious what the outstanding ASs or AS5 does as well if you connect the dots..

My Mariner is getting shipped within Canada and it's coming via Vitran Express.
I paid $40 shipping and was told it would go to Vitrans closest depot.
With my tracking number email it stated that I be home on the expected date of deliver so I can help the driver unload my box.

I guess we'll see where it ends up.

A 48v 20Ah battery will likely cost almost twice as much as a 48v 10Ah battery, so the benefit is not cost savings, but convenience of not having to carry a spare battery.

You could buy two 48v 10Ah batteries (to double your distance) and bring the spare only on long trips.

Better yet, since the price of the battery alone is already around 40% of a complete bike, you could justify buying another bike for a family member, and "borrow" their battery when not riding together.

For example, the 48V 10Ah battery for the Yukon 500 is listed for US$550 today. I would estimate that a brand new 48V 20Ah version (if available) will cost around US$1,000. For US$350 more, you could buy an entire new Yukon 500 (US$1,350) with the battery included!

Also, the smaller 10Ah batteries will be lighter. If your routine includes a stopover (like the office), simply keep the extra battery in the office to swap to double you distance.

Carrying a 2nd battery -
• A 48V 20ah battery is believed to deliver approximately 100km/62 mile range!
• It won't have to charged as often that may increase its life.
• I could be wrong, but I assume that if the battery is purchased in quantity the battery won't cost that much more:
Example 2.

It's inevitable for battery tech to improve resulting in more power and greater range.

Are these battery definitely compatible with the Mariner? Since my Mariners expected to arrive by the end of this week and I have no experience with it thus far,if i am using moderate levels of PAS with occasional moderate hills (nothing too crazy). How long will the mariner included battery last in terms of total distance traveled averaging 12-15 MPH, of course leaving a bit of charge left at the end of the ride so I dont end up walking the bike home the last 5 miles.
Are there currently GOOD HIGH QUALITY cell 48 Volt 20 AH battery that are currently available that would be compatible. I don't recognize the brand name of the one mentioned, and I would be hesitant to purchase. I sure hope Volt offers this choice in the very near future both as something you substitute for there current battery they offer when purchasing their bikes and also in accessories for people that already own one of their bikes.
Your Actual Milage May Vary

The distance that the bike can traverse depends on a number of factors.
Such as terrain, overall weight of the bike, tyre inflation pressure et al.
Generally, a 48V 10ah battery will render approximately 20 t0 24 mile range.

A number of ebike manufacturers are now offering multiple battery options.
Enabling the bikes to be ridden farther.

Greater range is now a thing.

I like the forward pivoting seatpost as a means to quickly access/remove the battery. It would look to be a useful upgrade to the Radmini or the Voltbike Mariner bikes. Any thoughts?

Running out your battery is a great way to get an extra workout in. Hills are fun until you need to go up them and gravity kicks in on a 50+lb bike has been my experience so far. Not terrible on flats, you just don't go as fast. I have a Volt Mariner.

@zap016VOLTAGE I was just wondering when you started to notice your battery start to degrade on the Mariner if you happened to recall?
You happen to know how many miles you've put it so far with no battery degrade? I figure I have lost between 10-15 km's on a charge. Still looking for a possible source of the issue. Could be the lights, could be the rain, could be a tad heavier winter rain gear load. Overall, there still seems to be some battery overall loss though. Will be doing a battery swap soon to see if is my bike or the battery.

I ordered a Mariner from this shipment. Might get lucky and have it by Friday.
I wanted green but I got white instead due to black being the most popular.

I'm thinking of painting it satin brown...wonder if that would be an issue with warranty.
Did you receive your bike or have a tracking number yet? I also ordered, and was just wondering about the turn-around time......

Hello, I'm thinking of buying an electric bike to ride to work and I'm looking at the 2015 prodeco mariner 8 and ejoe epik we. Which of them is a better choice consider the price specs, and warranty? Thank you.

+Tuyen Nguyen I like the integrated e-Joe battery and suspension fork. You get pedal assist as well as throttle on that bike and the fenders and rack are pretty useful so it's a winner all the way around in my opinion

That's a bummer! They offer a solid 2 year warranty... I think they would help you out if the motor is having issues and you haven't voided the warranty in any way. What do the noises sound like, is it something you could film and link to here?

Hello Sir !  i'm going to upgrate my i-zip i and was wondering which one would you choose from this 2 bikes: the prodeco mariner? or the cyclamatic bicycle electric foldaway ?
2 years ago

Good question! I've never tried the Cyclamatic before but it appears to have a rear mounted hub motor and includes fenders and a usable rack with the battery placed near the downtube vs. the rear. For all of these design reasons I'd go with it but considering that ProdecoTech is a large well known brand they might be better for getting customer service and having a warranty. I hope this helps! By the way, this is the image I was using for comparison, if this is not the bike you meant please let me know and share a link so I an provide more thoughts:

Hey Christopher, for some reason it won't let me respond to you with a reply (You might have replies turned off?) so I'm just making a new comment. While these bikes are repairable and do work alright, I'm less of a fan when it comes to the high center of gravity and plastic case that can crack and fall off (I've heard this from several shops). Another inexpensive folding ebike that is better in my opinion is the Epik Ejoe and it comes in two flavors (one with rack, fenders and lights for city stuff and one without that's more for off road riding). I haven't posted those reviews yet but the bike is solid.

Nothing against ProdecoTech, I just think your money will go further with Ejoe in this case. If you do get the Mariner 7 I think you can order straight from their website and have it shipped direct. You'll have to do some configuring with the handlebars, maybe true the wheels but that's true of any online ebike :)
