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

Here is a recent but incomplete list of world In addition to those on the list the is made in Vancouver where Grin also makes their modular using LG MG1 cells but I'm unsure if those are manufactured in LG Chem's Holland, MI, plant. The was by Procycle, eVox ebikes are assembled in Quebec but I'm unsure if the motors and frames are themselves made in Canada and the Dyname motor isn't available as a kit. Prodecotech have a final assembly line in Florida but use imported frames, components, and motor/battery parts. As J.R. mentioned above companies like Pedego and Trek do in-house design in the US but the bikes and components are imported. I'm unsure what other US or Canadian made battery cells, BMS boards, controllers, displays, wiring harnesses, bicycle components etc. are available, other than a few ebike specific parts made in small machine shops like Luna but there are several US steel frame builders and you could DIY assemble a somewhat made in North America ebike albeit many of the components will be imported.

ProdecoTech is a US company. They build their bikes in Florida in a real factory. They've even used US made frames on a few models, but I don't think that's true of any current models. I think they do more in the US than any other ebike company. Next is probably Pedego. Trek and Specialized are both US companies. It's likely their bikes are "designed" here.

I just hauled off and bought an e-bike. It worked pretty good for two years (with warranty repairs needed), soon after the warranty expired, so did the motor. Prodecotech will not support it now, they don't use the same motor. I would recommend getting a Trek e-bike, they have dealers and are well-supported. I would get the Cross Rip+. I know, its 4k price is steep, but that is the cutoff, unless you want a significantly heavier bike.

Of the bikes on your list, I think the Volt is the best choice. The Radcity is slightly better bike, but the size might be an issue (and they are out of stock of the step-thru). I would stay away from the Addmotor, and in my experience, the folding mechanisms on a lot of folding bikes is sketchy, so I would rule out the Ness as well.

If you could stretch the budget to $2K, the Prodecotech Genesis step-thru is spec'd incredibly well for its price.

Hi Mike,

I saw your note about wanting a replacement battery for the Outlaw SS. (BTW- Awesome bike! That is my own personal ebike as well!) We only sell the extended range version batteries now which is the 48v/12Ah version. The cost is $799.95 with a $50 flat rate shipping fee or $849. Let me know if you would like to order this and I can help you take that order directly over the phone.

Thanks and best regards,

I hate it when manufacturers won't give a weight spec. I guess to the average consumer, it would be a scary number. But this model looks to be in the low 40's, according to a review on Amazon. I may have to buy soon, because my Prodecotech Scorpion 27 is crapping out. I tried to request EBR to review the Schwinn Sycamore, but the contact form didn't seem to work.

GreenBike USA does now have a GB500 fat tire model. I have 2 regular GB500's and we love them.

I do know that Prodecotech is looking at releasing a few 28mph capable ebikes that are full suspension (1 fattie and 1 mountain bike) with NuVinci gearing in the rear and powerful mid-drives. I believe they release in the mid-March 2018 timeframe.

Prodecotech is planning to do some reviews with Court and EBR for our upcoming 2018 models here in early spring of this year. The Genesis R is a great bike with great reliability and is throttle based. Expect 25-30 miles typical mileage and a comfortable riding position with high quality components due to Prodecotech's history with some of the leading industry brands. The downtube Samsung battery is very reliable and powerful to keep the bike going for years of hassle free enjoyment.

Court charges a modest fee plus travel expenses, though they have national distribution through Dick’s Sporting Goods so it ought not be too much trouble. The newer Genesis and Phantom models with the frame mounted batteries offer better weight distribution than the older rack mount design. The website has mentioned an upcoming mid-drive model with a torque sensor pedal assist for a while, which would be a change from the direct drive throttle Class 2 ebikes they’re known for, though if it’s using the Bafang max drive 350w $3k seems a bit expensive when compared with other ebikes with the same motor from Biktrix, M2S, Populo, FLX, etc.

The ProdecoTech Genesis R is one of the bikes I’m considering. I really value the EBR reviews but there are not any recent ProdecoTech reviews. Does anyone know why?

Made in the US is not accurate. Assembled in the US is more accurate since their home page shows this;
From what I understand, the frame is the only thing made in Florida.

I would caution anyone from buying a bike direct from Prodeco. I own two Mariner 7's that I purchased through a bike shop, and was happy with them. Giving these bikes to grandchildren and needing step-through models, I purchased two Stride 500's directly from Prodeco. M.C., senior national account manager, was happy to take my order on Aug 25, 2017 and instantly charge my credit card. He suggested by bikes would be shipped within a week. On Aug. 29 I called because I had no tracking number nor even an invoice. He sent me an invoice with a shipping date of Sept 1. The bikes finally shipped Sept 22, after I threatened cancelling my order and disputing the credit card charge (I stress the need to use a credit card such as AMEX which allows charges to be disputed and money refunded). Others at Prodeco promised delivery dates but did not follow through: D.A., vp business development and L.C.

The bikes finally arrived. The Stride 500 has a Promax 25.4 Cruise 600mm adjustable Handlebar which requires a 6mm t-handle wrench to attach to the frame. (Neither the manual nor "quick start guide" have been updated to show this handlebar.) This critical tool is missing. Attempting to ride the bike without sufficiently tightening the handle bar is potentially life-threatening. Contacting the online support about this went unanswered. I had to threaten a BBB formal complaint before the tool was finally shipped. However, the e-mail confirming shipment stated "The tools were shipped this morning. It was not an easy task as they were discontinued 2 years ago, but we did find them and got them in for your bikes. 2 #6 allen head full size tools were sent." So even though this tool is necessary and specified in the assembly instructions, Prodeco does not apparently intend to include it. I have filed a safety complaint with the U.S. Consumer Product Safety Commission (CPSC) on this issue.

On a related issue, I believe it took my negative BBB review to get them to ship a replacement battery, ordered before my new bikes, for my Mariner 7. Prodeco bikes are well-built (if heavy) and are entry-level priced. Purchasing through a dealer who has them in stock may be appropriate, but consider the poor customer support and long delay in getting parts.

I love the look of the radmini

Thinking about selling my Mariner 7 and buying the rad

My question is which one do you think rides more comfortable---- the rad with the fat tires or the Mariner with the suspension fork ?

3 years ago

ended up buying a used mariner 7, think it is a 2013 model

riding on the dirt road by my house the battery set up rattles a lot and concerns me

does anyone have pics of the old mounts and the newer better mounts?

would like to see if it was upgraded or not
and deciding between contacting prodeco to buy a new set up from them or talking to the bike shop here about maybe fabricating something stronger

any suggestions/info would be great

Vincent - may I ask how you paid for the Prodeco Mariner 7? I know they go for $1400 retail. To me this bike is made to cruise around the marina hence the name. Since it's small with 20" wheels makes it limit to riding places like dirt trails or any kind of off roading. The huge rear battery placement gives it a high center of gravity making the ride less of a balance. From my experience with this battery placement, the bike will either sway too much to the right or left especially when you're standing and pedaling. It has a front wheel motor which will tend to make the steering a bit shaky and less stable. It's good for portability and to just cruise around like at a camp site or marine.
The Cemoto is just the opposite of the Mariner 7 with one thing in common is that they both fold. It has a larger 26" wheels, full size frame, rear hub motor, dual suspension and the battery placement is on the frame which evenly distribute the weight through out the bike. This will give it a more balance ride. You get the best of both world, portability and able to ride on or off road. It's much less expensive and for the quality it possess, you're really getting a good value for the money. What I also like about this bike is you're able to upgrade, so far I've added all kinds of accessories and upgraded parts. It's a bike that will grow with me for a long time.

so far really happy with the bike, rained a lot here today and is supposed to be rainy the next few days

but the build quality seems very good for the price

also bought a used prodeco mariner 7 last week
i was originally buying a new single speed mariner, but this guy on craigslist had mariner he wanted to get rid of that day and said he would take 200
knew it was not running, but had it repaired for 80 and they said it is a good bike

both of them just got home in the past couple of days so have not ridden either

in comparison folded up the mariner handlebars fold down so it is a little thinner and smaller because the tires are smaller
but the weight should be less on the mariner and picking them up i cannot tell

if the cemoto handlebars would swivel it would be perfect

sitting on the cemoto the bike just feels better to me, dont know if that is the bigger tires or what
feels more sturdy
it seems easier to get on the cemoto than the mariner also

hopefully it will not rain for the next 3 days and i will get to ride them a little

Hey Rich! Sounds like you're on the right track and I appreciate the details regarding your car size, RV and budget. I can see how an ebike might help you get out there in a fun but not overwhelming way to stay in shape and enjoy the places you visit a bit more thoroughly.

As you can tell fro my reviews for the and SE I really like these bikes for all the reasons you mentioned (price, weight balance and throttle + pedal assist). It's true that smaller diameter tires have a lower attack angle and are less ideal for bumps and rocks but the SE has that nice suspension fork which helps along with the wider tires. During my ride tests it felt stable and I also didn't experience any speed wobble. I personally wish e-Joe offered the gears and rack of the Lite with the suspension of the SE... Maybe they would do a custom order for you?

Of all the folding ebikes I've reviewed the e-Joe's are my favorites and some of the only models under $200 with shipping as you specified. I prefer to keep my bikes inside (out of sight) and with your car and RV that's going to work well and it will also keep them clean and dry. The only question is height and weight because as jayvan mentions, the full size feel is nice at times. For me being 5'9" and 130lbs the smaller step-through design of the Epik bikes is fine. Your thoughts on a DC to AC converter are also spot on and I recently that has been working well (I'm on the road right now myself).

You may have already discovered the section of the site but if not, feel free to sort through. The other two models that come to mind are the (I'm about to review the F350 which has a more powerful motor) and the which is less balanced but still has the suspension fork and an affordable pricepoint.

I love the sound of the motor of this bike , i bought one like 2 years ago , and change the frame to another foldable with double suspension with front and rear disk breaks , the battery sadly in my backpack , but any way , become a monster but with the angelical sound of his motor ... max speed 30 mph , i will not flight to the future but is god enough , still under torrential rains ...

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 ?
4 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 :)
