Best strategy for v. steep hill

I live at the top of a longish, very steep hill on a dirt road. I am older and not very strong. My Rad Step-thru can't make it up the hill without very vigorous all-out pedaling. i put the assist on 5 and the gear on 1. With the wattage already maxed at 750, the throttle is pretty useless. is there anything i can do to increase the power of the bike or other setting that might be better? I like the bike under relatively easy conditions, but I expectred more and am somewhat disappointed.

You could look at replacing your bike with a powerful mid drive like the Bafang Ultra or BBSHD. In low gear I can pretty much throttle up any hill with my Ultra. Uses a lot of battery but conventional wisdom is mid drive is the way to go for steep hills since you can leverage your bike's gears. If you just need a little extra help maybe something like this might work?

Rad City step through, right? Not the newer step through Rover? I ask as they use different drive types.

If it's the 'City, you might try hitting the hill a little faster if you can do that safely. The motors make a little more power at speeds over 10-12mph. Below that they are gutless. I was pretty disappointed with mine as well. Been quite an adventure, but after a series of modifications, it's now able to put a grin on my face under about any conditions

So other than trying at a little faster speed, there are other options, but none are free.

I'd be surprised to hear you were having trouble with a Rover. -Al

Thanks, but I am not looking to buy a different bike, just looking for a better strategy for this one ... if there is one.

Sorry I can't help as I don't own a rear hub. I bought a cheap rear hub, burned it out on my first ride up a steep hill, returned it, bought a mid drive and never looked back. It is interesting to see folks say their rear hubs do fine on hills, although guessing those are geared hubs. Sounds like you have a direct drive as opposed to a geared hub so double whammy for you. Good luck.

Thanks. It's a long very steep hill. and yes, i have the step-thru. What are the other options--for this bike.

He knew you have a step-thru bike.

However, he was asking if you have the Rad City Step Thru, or Rad Rover Step Thru. :)

Get a 35A kit from Bolton or Electro Bike World.


48 x 35A = 1680W

Much better than the stock 750W.

I didn't realize Tomdav also recommended the Bolton kit.

He was not suggesting you to buy a new bike, there's a company called Bolton that sells 35A controller kit that amplifies your power up to 1680W.

Electro Bike World also sells that kit as well.

Hello Tallenvt!

I’m having the same problem (see my post in Introductions) with my 2020 RadMini step thru. I thought I had a 750w Bafang motor, but it’s only a 500w Bafang!! I would do what I did and email the MOTOR manufacture the serial/model number to find out. Also, Kyle at Bolton bikes has a controller & color monitor upgrade for around $200 that should give it more power.

Hope this helps. Let’s us know what you do.

He most likely has the Rad City Step Thru, not Rad Rover Step Thru..
You're talking about Rad Rover Step Thru, which comes with over-volted 350W Bafang motor.

The Rad City Step Thru comes with Shengyi direct drive, which still is compatible with Bolton kit, but it is not Bafang.

Mines a Rad Rover step through. I check on a few vacation properties when they are vacant and one of them is at the bottom of a very steep fairly long driveway. I just make sure I'm in first gear when I get to the bottom. When I leave I put it in PAS 5 and zip up it with very little effort at all and I'm 71. I've tried it in PAS 4 and it's a little more difficult but doable. It's actually pretty much the only place i even bother with 1st gear.

You may draw some better answers to your question by telling us WHICH STEP THROUGH you purchased. It does make a difference. There are 2 choices, and one of them is pretty gutless by nature.
