8 years agoNice to see Magnum upgrading some of the features on their newer ebikes. I love my Ui5, but I do wish it had the throttle with full power at all times, the higher voltage battery and some other features found on this new model. Ebikes just keep getting better!

8 years agoI see Magnum making incremental upgrades to their products and it’s exciting to think of where it will lead. Even today, I feel like you get a lot more bang for your buck than just a year or two ago. And yes, with the throttle settings and better display I like how it empowers riders to choose vs. limiting them or requiring extras steps. In short though, it sounds like you’re enjoying your Ui5 and I’m glad to hear that :D

8 years agoHi Court, I love your website and your video reviews! I’m short (5’1″) and a big fan of non-elecric folding bikes, and this is the first folding electric which has peaked my interest. I live in a hilly area of Northern San Diego, and wanted to know if you would recommend this bike for hilly areas.
ReplyThanks in advance for your reply!
Court Rye
8 years agoHi Susan! Yeah, the Magnum Premium could be a good fit for your area. It’s much more powerful than the average hub motor driven folder, priced pretty well and comes in that deep step-thru configuration. As noted in the review, it’s heavy but depending on your needs (and a bit of help) it can work great for a wide range of uses. I continue to hear great things from shops and owners about Magnum and am seeing their brand grow significantly in the US which also gives me confidence. I hope this helps! You could also chime in at the EBR forums and ask for feedback, maybe people who already own their products will share.

8 years agoFor a folding e-bike, this is a rather heavy bike at 61 lbs. The primary purpose of folding is going to be ability to put in compact spaces, carry on a train, or easily place in a car, or easily carry up steps into apmt or condo, so this ebike is a just not a very viable candidate for those purposes. Also, at 500 watts, and 48 volts its way more power than an ebike with those size tires and the likely speeds anyone would want to travel at, especially for the purposes of what most foldables are chosen for. The price point is also a few hundred dollars more, than more viable and purpose designed foldables. I’ve tried this and the Blix Vika’s and felt the Vika’s were actually sturdier, and gave a more confident and secure ride. Plus their models are 48 lbs and 36 lbs, respectively, which better suits the purposes most riders searching for foldables are seeking.
ReplyCourt Rye
8 years agoThanks for chiming in and sharing your experiences Mark! I appreciate your perspective and am sure others will too. I like the Blix products and was excited to also see the lower powered, less expensive Magnum Classic as an alternative to the Premium here :)

8 years agoI went and bought one of these, and it’s been very nice- one thing I wish they had was a manual that reflected the actual bike’s screen, which is not at all what they show in the manual. I’m trying to figure it out as I go… it appears that the 20-inch wheels may be limited to a top speed of 20 miles an hour, but I’m not sure what that screen is. I think it’s the 4th one… it shows 2 numbers, one of which seems to change the bike’s top pedaling speed, the other of which I’m not sure about. Possibly wheel size? Scratching my head here.
Aside from the instruction manual not helping at all with learning the settings, it’s a good bike. The rear wheel’s not easy to remove if you get a flat there, and the tire takes patience to get back on afterward. As far as flats go, the folding is a godsend if you need to call someone to come pick you up and get out of the rainy roadside.
But on the positive side, the range I’m getting out of it is at LEAST 40 miles with pedal assist, and around 2 bars of battery left after a day of riding. It’s been handy for small grocery runs and has given me the freedom to commute locally, which is a good thing for someone without a car and no public transport in town.
20 MPH has been a good, serviceable top speed for me. It’d be nice to get it a little faster as advertised, but I’m fine with this.
I don’t find myself using the throttle for more than short bursts, at times when I want to get off the line quickly such as crossing roads or starting on steep slopes.
Pedal assist 2-4 are most comfortable for me in terms of just riding around, 1 is good for starting up or just taking my time, and 5-6 are nice and effortless ways to get somewhere fast.
I’ve used the USB charging from the battery, and my Samsung Note 4 tells me this battery is only capable of slow charging- turns out to be maybe half the speed of its normal charger, if that. But getting 40% of my phone’s battery recharged did not seem to tax or noticeably drain the Magnum’s battery at all, so for topping off electronics or charging stuff like a Kindle as I ride to my favorite reading spot is perfectly doable.
On another note, no reading or texting on-bike: even without doing these things I managed to WHUMP! myself into a signpost and a parked car in the month I’ve had it. The bike and I were both fine after each incident, aside from the usual shattered-dignity bit. :)
I tend to ride my bike in Eco mode (Settings screen 5- hold Set, press Set until you reach screen 5, and press minus to toggle between the three modes), just because I want this battery to last, and because so far I can’t tell a difference between that and Normal in terms of acceleration or top speed. Still trying to figure this one out. I’m not sure how Power mode differs either.
It’s a fun bike, and is turning out to be pretty practical whenever it’s not outright raining (in which case no bike of mine is going outside for long.) I’ve even gotten some interested questions from strangers at the bike rack. It’s weird how much more expensive people around me tend to think it is, and how much slower and shorter-range. It feels good to give ’em a pleasant surprise with “Yes, it’s electric. …20 miles an hour, 40+ miles range. …Yes, it folds. …$2000 including tax.”

7 years agoHi Court … Vik from down under… How do I get a couple to Australia with out the price of another bike as postage…??? A his and hers package…!!! I’m 100 odd KG and the missus is about 70ish ,so a Classic would do her, or stick to both premiums for the better suspension and bibs and bobs…???
Over to you Courty me old mate… vik… Adelaide South Australia…
ReplyCourt Rye
7 years agoHi Vik! Sorry for the late reply, I just got back from Interbike and am playing catch up. I could be mistaken, but I believe Magnum may be offering some of their products in Australia. Perhaps you could reach out and ask them and get connected, then you could get the bikes and not have to pay all of that shipping. Let me know what you find, I can help reach the company if they don’t reply to you for some reason :)

7 years agoHello everyone. Has anyone come across a delimiter for the magnum premium?
ReplyEric S
7 years agoI’ve reviewed this bike before, 10 months ago, but I think it’s a good idea to come back and leave this one too for comparison. My last review was still that of a new owner; this time I’m going to share all the things that have gone wrong since then. Before I go another sentence into this, however, know that I *like this thing,* and the only reason I’m focusing on what went wrong is because it’s been nearly everything I hoped it could be, and I would not trade this bike for any other. It is because of this that I want to focus on what made it less than perfect for me, and how it was to deal with the kinds of problems that arose during my ownership of the Premium.
First: the good: see my other review. It’s a hoot, this thing.
Next, the awkward: 20-inch wheels provide a pretty crappy angle of attack (lower is better) for broken-up sidewalks or terrain like that which I ride across when I go to work. So if you’re going across potholes with this, or sidewalks with the squares sticking up every which way, slow down. Way down. One good jolt can pop the tires. Bikes with bigger wheels usually don’t have as much of a problem with the same terrain, I gather. Also, the wheels with their tube lengths aren’t a size that the local Trek store, the only one near me, has, so I do have to order my replacement tubes ahead of time. And when it comes to replacing… yikes. This is *not* a bike you can just pop the flat or the wheel off, change, and have it back on at the roadside. The back wheel doesn’t like to come off, and …well, I believe I addressed the details of the tire change in my earlier review. I stand by what I said then. The only thing I have to add about flat tires: it’s always, always been the back one. Never the front. 7 back tire tubes later, I’m still running the original front. Oh, and the Trek guys recommend thicker “thorn tubes” for the tires of this e-bike, just to make it tougher to puncture and hopefully pinch. Keep at 60-65 PSI, or you *will* get a pinch flat, unless you are just that much magically better than me as a human being. In which case, teach me. :)
So I covered the tires. Now, rain: light rain or drizzle is fine, I’ve ridden through that many a time with no ill effects. Moderate rain, I try to avoid, but that hasn’t done more than make it squeaky for several days. Heavy rain… ugh. Got caught in an intense rainstorm during a vacation over the summer, and after the storm, the throttle quit responding reliably or at all, it always wanted to creep forward at 1 mph, and any gear was treated as 20mph pedal assist. I let it dry for a few days and kept the controller unhooked and in a bag of rice for a week, and eventually it calmed down. I shall never let that happen again, and strongly advise caution in rainy times for others.
Now that the rain’s been covered, here’s how finding tech support or parts went: not well. No shop, including the one I bought it from, offer maintenance or help with the electrical bits. The controller (Das-Kit C6) is abominably hard to find, and I still haven’t found a spare. And the manual tells me crap-all about the settings- both the C6’s manual and the Magnum’s manual, which in fact depicts a different controller than mine has.
Speaking of controllers: mine came with a Das-Kit C6. That’s different than the one that the manual shows, as I said, and it also has a crucial difference I want Court to know: the C6 only lets you go up to 20mph, period. When paging through the controller’s settings, one of the screens lets you set wheel size and top speed without it or the manual saying which is which. The middle number is the wheel size, and should be set to 20, and the number on the left is the top speed, apparently. It never goes above 20 at any wheel size, unfortunately. So I can only surmise that if you want your Magnum to go 25mph, you’ll need some controller other than the C6.
Finally, this thing is fun, and any difficulties I’ve had with it are not the bike’s fault. It has stood up well to daily commutes to work in all weather, rides down dirt trails and grass, through puddles and shallow streams, and has no lasting marks aside from a paintless crescent on the battery scratched by swinging keys.
This has been, essentially, my experience gained with my Magnum Premium over the course of 2017. And it’s just getting back out for 2018 now.
ReplyCourt Rye
7 years agoHi Eric, what an awesome comment! Thanks for going in deep and expressing the challenges in such a constructive way. I especially liked the bit about how the swinging keys had made a crescent scratch mark on the side of the battery pack, lol. I try to touch on some of these potential challenges in my videos (like pinch flats) but haven’t gone in depth or been as directive in how to avoid. As a relatively lightweight guy who rides mostly brand new ebikes, it’s easy to forget about those shortcomings… and how difficult the hub motor wheels can be to remove and service. I’m glad that you’re figuring out solutions to keep your Magnum Premium on the road, the inner tube tip and display feedback is excellent. Thank you!

6 years agoMAGNUM Premium 48: I am 240 pounds and live on top of a very steep 350 foot high hill with a rise-to-run of 1:6. I am capable of supplying 60 watts continuous from my legs. (I am old). Will this bike get me up the hill?
ReplyCourt
6 years agoHi Steve! My guess is that yes, it would get up the hill if you bring some momentum on the way in and pedal continuously in a low gear while activating the highest level of assist (or using the throttle). I cannot say for sure but my thinking is that the bike will work out great and you can always keep an eye on the tire pressure (higher within the range listed on the tire sidewall will be more efficient). I hope this helps, maybe also check with Magnum directly to hear their thoughts :)
ReplyBen
5 years agoI’m really having a hard time choosing between the Magnum Premium and the Radmini…. Either I get a Premium at my LBS and have that local support as well as 25mph top speed, or order a Radmini and get the nice off road tires. Oh the trade offs…
Court or anyone else: do you prefer one of those two bikes over the other?
ReplyCourt
5 years agoHi Ben! As much as I love Rad, I’d probably go with the Magnum because of the local shop support. Both of these are great bikes, but I also like the slightly faster speed and feel that Magnum has done a great job with their products in recent years :)
ReplyBen
5 years agoThanks Court. That’s probably what I’ll end up doing, it’s the most practical and it’s a fun bike; went for a test ride the other day!
Do you know of any updates to the Premium in 2020?

4 years agoCan you use a Yepp child seat on the back rack of the Magnum Premium folder?
ReplyCourt
4 years agoGood question, David! I’d double check with Mangum directly… but my guess is that a Thule Yepp Nexxt Maxi would be the only one that MIGHT fit. It clamps on from the sides vs. slotting downward. Magnum uses a fairly standard rack here, and even though it’s not super tall, I think a child seat could still fit. It seems like the seat would be far back enough that the child would be safe from getting kicked, just be careful and double check with Magnum ;)
