GENERAL NOTES ON RANGE: Predicting range depends on a number of factors: eg. someone who weighs about 70Kg, riding across varied terrain with moderate undulation and a steady cadence of 70-80 rpm can control the range through battery management using the mode settings afforded by the control system. He/She could expect to get anything between 80-120Km from a single battery charge. Visit our FAQ Page for more general Q&A’s.

NOTES ON WEIGHT: A really lightweight mid-range e-bike weighs in at around 21-23Kg, provided its a standard 250watt mid-drive motor model with 300-500Wh battery. A super light carbon MTB e-bike with roughly the same motor and battery might come in at 18-20Kg. For instance a top end R 150 000 ($10 000 USD) Specialized e-bike weighs just over 20Kg. The weight is a consideration if you need to transport the bike on a rack or in the back of your vehicle, but removing the battery might save 4-5Kg already when attempting to lift the bike. Either way, at the moment there is not really a significant difference in weight between most of the available e-bikes in the market. Darrvin’s lightweight aluminum-alloy frame and compact components make for one of the lighter e-bike configurations out there in its price class and with the battery removed is an easy lift onto any bike rack.

After riding a regular pedal bike to work for the past seven years year-round, I was reluctant to get an e-bike. But, I couldn’t justify my sometimes 40-km commutes anymore when they took up a significant amount of time that I didn’t have and left me a little too tired to participate in the activities I was meant to do to begin with. I was tired of getting buzzed by cars going 100kmh up some very steep hills I biked through. I didn’t want to deal with headwinds in the winter stopping me dead in my tracks up and down those steep hills either. I purchased this bike to have zero excuses for not biking to work and zero excuses for not camping with my bike all the time. After I got used to the bike and felt comfortable with the ability to keep up with traffic over hills going 30-40km kmh, I sold my car.

This bike will push you to be a better cyclist. I had some doubts in typing that line but this rig will teach you to take risks, corner harder, and be more aware of upcoming obstacles. This bike is wicked fast if you ask it to be. That being said, I go out on the eco setting and the bike is perfectly at home taking the bike path at 20-25kmh with the eco assist. With three different power assist configurations, you will be able to ride as slowly or as quickly as need be with your mates and work out as hard as you please.

Did some online research on the Yamaha Wabash and some of the other similar e-bikes when I stumbled upon the Darrvin Evolve. I received the box from the company and it looked like the bike had been built and adjusted and then re-boxed as it built up easily and after putting the front wheel, seat post, handlebar and the seat post in and a quick charge it was ready to go.

Assist up to 35kmh is great when needed but your really have to work to get your speed there and then keep it up so don't think it's a free ride. It's a lot of fun to go whizzing by traffic in the bike lane on my commutes and I do feel like I'm getting some exercise, but I'm sure time will tell on that. The bike does ride smooth with the motor off although you do feel the added weight of the motor and battery.

I put some Planet Bike fenders on it since it's wet in the spring, they mounted easily and don't rattle at all. I've already started using this for most trips under 20km and will start taking it out on the gravel once everything dries out.

Loved it. First time ever on an e-bike and really enjoyed it. It takes a little getting used to at first and to be honest, I wasn't super thrilled about e-bikes in the beginning. But this bike changed all of that for me. After riding it my opinion completely changed. Loved the ride, loved the boost uphill and into the wind, and the three settings to make me go faster just a lot of fun. Initially, the only thing I didn't love was the idea of all this extra battery weight (in case the battery ever went bad) but with the battery out it’s easy to lift and handle on and-off my bike rack. Overall, loved the ride and enjoy this bike tremendously. If you find a better ride than the evolve, at this price, I’d be skeptical. The price convinced me to try it and I’m very pleased with my purchase. Two of my friends have since also purchased the evolve and we such fun weekends going out for rides. We can stay ahead of the traffic and it’s the best money spend!
