3 months agoIsn’t the price $1299? (Not $1499).

3 months agoYeah, thanks for the heads up Bryant! I made a mistake there. The price has been updated to $1,299 as you suggested :)

ReplyCourt
2 months agoHi Timdeck! I didn’t measure it… but perhaps someone in the forums could help? Rad also does a great job with support if you contact them through their website :)

2 months agoCela pourrait vous convenir, la version canadienne utilise un moteur de 500 watts, le cadre est très accessible avec une faible hauteur de support et les pneus larges offrent une stabilité et un confort accrus.

2 months agoIs there different motors from Canada to US versions? 750 vs 500? Or is the Canadian version dummied down to 500 using the controller? If so I am wondering if it could be unlocked, for off-road use.
ReplyCourt
2 months agoHi Jay! Good question, and I’m not sure on the answer. My guess is that it could be controller based, but the Rad displays have become more locked down in recent years. I think at a minimum you would need the LCD display panel to unlock anything. Perhaps you could ask around in the Rad Ebike Forums.

2 months agoThanks for the great review on the expand five. Do you think its big enough for 6’2″ rider? I have a rover now but want the flexibility to put into the back of my suv.
ReplyCourt
2 months agoHi Jonathan! I think that most of the folding bikes are going to offer a similar experience since they’re mostly one-size-fits-all. The good news is that the fat tire designs tend to be a bit larger overall, and higher off of the ground. What I like about the RadExpand is the sturdy folding joint, heavy duty buckle system, the rigid steer post and stem vs. telescoping. It seemed very solid to me, and with the seat raised up, I think it works well even for taller people. Given the cadence sensor pedal assist and throttle, you might not need to get the full leg extension like a road bike. I think the stock seat post would get close for you, but that’s an affordable and easy part to swap out if you need an extra long one. You might be able to ask Rad Power Bikes support about your height and weight to get a more official answer, but these are my thoughts :)

1 month agoI am 5’4. Will I be able to get a proper extension of my knees? I have had knee replacements on both sides, and am used to being able to straighten my legs while riding road bikes. I should also mention that I am in my 70es!.
I noticed in the videos that neither you or the Rad technician had straight legs while riding the Rad expand 5.
ReplyCourt
1 month agoHi Karin! Good for you, staying fit and riding bikes is a wonderful thing to do at any age. Yes, I do believe that you’ll be able to get full leg extension on this electric bike. I did not raise the seat post as high as I could have because I like how it looks better when I take photos if the seat is a bit lower. I am also someone who likes to get nearly straight when I pedal through a downstroke. I’m 5’9″ and have pretty long legs with a 31″ inseam, so I am pretty confident that you’ll be able to achieve it too. Great observation skills, and I hope this feedback helps you!!

2 weeks agoGreat review, thanks. I’m 5’2″ and looking for an ebike for forest dirt/gravel roads in Oregon. I wonder if the bike will work well in these conditions. Is the steep head tube/handlebar angle an issue? I do a little technical MTB type riding but primarily enjoy cruising forest roads.
ReplyCourt
2 weeks agoHi Kathy, I think the RadExpand 5 would offer plenty of stability and traction for gravel roads. Given your height, the lower frame and approachable step-thru design might be a great benefit since this and most ebikes weigh more than regular bikes. There’s no suspension fork, so going fast on very bumpy and technical sections could be jarring. The larger tires will offer some comfort if you don’t over-inflate them. Long story short, you could go for this or the RadRover Step-Thru which doesn’t fold and is much larger. Otherwise, you could spend more for a product that uses higher end components like air suspension.
