I think it's ok to say that Radpowers have a lot of problems that better built and much more expensive ebikes don't have.

No I think evil_bunnY likes suvs and fat bikes, just not ebikes with fat tires, probably because they aren't expensive enough

Test rode the Riese and Muller Load 60.
The handling and suspension were great, but the Bosch Cargo Line motor seemed to be really torque-limited. It just had no puff when I dialed the enviolo into higher gear ranges.
An Urban Arrow I could get up to 25mph pretty easily, and here, I had to pedal decently hard to get it to 19.
On a steep hill test, I was really mashing to maintain 9mph. In a scenario where my effort alone would be maybe 5-6mph.
It was weak enough that I didn't think it was enough to justify the extra weight of the motor and battery.

Brought it up with the store, and they thought the bike was all properly tuned up and updated, but that maybe it was defective in some way. If this is the default setup, I'm really surprised.
Because it's got rear suspension, the belt is run through a tensioner. I wonder if that plays into their decision to limit the torque.
I didn't bother trying the Load 75 they had -- it's just too long for my needs.

God bless it, I took my Gazelle to the shop because my rear tire was swiss cheese and the self sealing tube was leaking. They replaced the tires, trued the wheel, bled the brakes, replaced the shifter cable and housing, updated the firmware, but what's still there? The same drat inner tube!

At least the owner was really nice and offered to comp the labor if it starts leaking again.

The amount of dumb stuff i'm seeing in the Rad Power Bikes reddit these days is crazy. There's a dude running motorcycle tires on his Rad Wagon under 25 psi and wondering why they're coming off the rims . I understand the tire situation sucks, but there's so much bad information over there.

Joined the ebike community this weekend! With a recent move I am able to bike commute again so after a few months of riding my tired Karate Monkey 15 miles a day we sold our second car and put that money towards a HSD P9 performance. I've only logged about 20 miles so far but loving it so far. This morning I was able to load up all our laundry (currently doing our laundry at work) without issue and the bike handled the weight like a champ, can't wait to try some heavier loads.

Feels great to be a one car household again and I feel good about our purchase, we tried several bikes and the Tern HSD felt like the best choice. Can't wait to log some serious miles on her and make some minor changes.

My Karate Monkey with the HSD, keeping the Karate Monkey for bike packing someday.

BICHAELING
I finally did something about the brake caliper alignment on my homebrew hub motor driven e-bike. The original plan was to make a new bracket, but it became obvious I could just modify the existing one. I measured the unused sliver on a worn brake pad, which was 2.5mm, so I simply shaved off 3mm on the adapter in the mill:



A small chamfer and thread chase of the holes and a kiss of the file to de-burr the part and it was ready for install again.



The disc sits visibly in the right place in the caliper at last! Sadly the pads have been impregnated with mineral oil from a leaking bleed nipple so I'll have to replace those before I have a good rear brake, but this should work now, even though there's less meat than ideal in one of the threaded holes. Still five complete threads should suffice, especially since it's all shearing force on the bolt. If it doesn't I'll fabricate a whole new part.

Rad Power has their Radmission for $499 instead of $1,199, and their fat tire is $1300 from $2k

Both are in my price range for a first time e-bike, any thoughts or experience for or against? I know the drawbacks of a fat tire but still see the appeal. Or wait a bit and get a Grizzly which may be way out of line from what I’m used to as a bike.

Rads are inexpensive and generally pretty well regarded, but if parts wear out or get damaged replacement parts can be hard to source and their support is less than stellar. I'd call some local bike shops and see if they'll even service Rad bikes. If yes, then that's a pretty good price.

I usually take every opportunity I can to poo poo on radpower, but of the cheap ebike brands you could do a lot worse.

Also, holy poo poo $500 is insane. You're not going to find a new push bike for much less than that.

50:16 is what I would consider a very high gear for a single speed bike. I would personally prefer something around 40t or 46t chainring, but I'm a snob about cadence.

On that bike, 80rpm, which I'd only call brisk, is already 20.6mph.

That is just motor gear reduction as opposed to direct drive not chain drive reduction.

I was considering the Grizzly or similar when I got the itch for an e-bike, but I ended up going with the Zooz Ultra Urban 1100. 2 months and 622 miles later, and I am not regretting the choice in the least. The performance is excellent, it's a blast to ride, and it looks amazing. The speed is a game changer for the roads I can ride, but it still looks like a bike for use of bike paths.

Given the non adjustable height and shape of the saddle, do you pedal it at all?

sigseven
May 8, 2003

You don't have to pedal if you don't want to, haha. The adjustment for longer legs is to sit further back on the seat, plus standing if you need to push hard. Just cruising with pedal assist it feels fine for me (at 5'11"), but yeah, it's not ideal for a full ride of hard/fast pedaling. I still have my regular bike when I want that.

Mainly I only use the pedal assist when I'm trying to stretch my range, help it up to speed a little faster, or look extra bicycle-y. Though I did see a post by some madman going 120 miles using only pedal assist level 1.

Yeah at $500, if it doesn't actively explode and works at all reliably it would have been your best budget option by a country mile. I shared it with my pops but he has realized that while he'd like an e-bike for his retirement trailer hitch, most of these are too heavy for his old rear end.

In the US the pedal-assist should stop at 20mph no? That doesn't really explain the low speed wimpiness tho. Our bosch motor on turbo is actually unmanageable from a stop, it pulls way too hard.

Well my wife and I drove down to the local Rad Power retail location and test rode several models. People were super cool and not pushy about sales at all, just made recommendations and talked about what we needed. Having not ridden a bike in years to riding the streets of Berkeley was a little panic-inducing but it went really well!

In the end we ordered a RadRover 6 Plus step through for me and a RadExpand 5 for my wife. They’re heavy as hell but manageable. Looking forward to them becoming our daily commuters since gas just went up to $6.50 in our area.

I thought you can't ride those everywhere you can like a class 1, but maybe you're right! In europe R&M only sells pedelec (25kph) and speed-pedelec (45kph, but crucially can't be ridden on bike infrastructure, and need registration+insurance) it appears this maps to class 1 and 3 on the models they sell in the US.

I think it depends on the state. For example, they seem to be expressly forbidden in New York.

In Massachusetts there is no specific provision for class 3 ebikes in the relevant laws, so it's not totally clear, but that may mean that they're illegal or need registration as mopeds or something technically.

Also IIRC the way class 3 is actually defined they probably can't actually have throttles at all so must "class 3" ebikes aren't actually class 3 at all and are probably illegal everywhere (people are deliberately misinterpreting it as allowing higher speeds on a bike with a throttle as long as the throttle cuts out and you can only use pedal assist at those speeds).

So long as you don't ride like an rear end in a top hat you generally won't get hassled. 1000w BBSHD's are over the limit in every state, but they are everywhere and I haven't heard of people getting their bikes confiscated. If you're going out on shared trails ripping around and doing wheelies on a sur-ron people will definitely call the cops on you though. Cops would warn you and tell you to stay off the shared trails. If you decided at that point to continue to gently caress around, then you probably would find out.

Interesting -- didn't know brands were selling throttled bikes running up to 28mph, but not surprised -- it seems to squarely appeal to people not coming from regular cycling.

I had committed this to memory early on:
Class 1 is assist only, to 20mph.
Class 2 is throttle up 20.
Class 3 is assist to 28.

Generally they are sold with a software setting limiting throttle to 20, but they have a settings menu where you can change it, disclaiming that it's only allowed on private land.

I was able to increase the max speed of my radrover6 to 24 mph in a 'hidden' settings menu. So loving glad I learned about that right when I got it. Don't know what I would do without it. It's literally +20% top speed.

If you're gonna have roads, you're gonna have roadkill.
I'm a big honkin' dude, so I recently got an Aventon Aventure to help me get some exercise.

It's great! I used give up at the slightest hill, but now I can push myself.

Around mile 80 picked up a screw, which was a whole ordeal. But, in the process of removing and reinstalling my rear wheel to swap the tube (tbh, I had a shop replace the tube. next time...) I realized I don't know how the gear system works. Which lead me to another realization: I've been rolling around in the lowest gear possible the entire time. I'm looking forward to shifting up gears to push myself further.
